d12101 | train | In MVP, it is the responsibility of the View to know how to capture the click, not to decide what to do on it. As soon as the View captures the click, it must call the relevant method in the Presenter to act upon it:
------------------- View --------------------
button1.setOnClickListener(new OnClickListener({
presenter.doWhenButton1isClicked();
}));
------------------ Presenter ----------------
public void doWhenButton1isClicked(){
// do whatever business requires
}
I have a series of articles on architectural patterns in android, part 3 of which is about MVP. You might find it helpful.
A: OnClick should call a Presenter method. You should do your business in presenter and if you need to update the ui you should define a method in your View and call it from presenter.
You need a method for your View ex:
public void showCounterCount(final int totalClicks){
counterTextView.setText("Total clicks so far: "+totalClicks);
}
Also you need a method and a variable in your Presenter:
int totalClicks = 0;
public void onCounterButtonClicked(){
totalClicks++;
mView.showCounterCount(totalClicks);
}
And refactor your code like this:
counterButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
mPresenter.onCounterButtonClicked();
}
});
For more complex and clean architecture you can do your use case business in interactors. (In your example incrementing a counter value is a use-case for your application)
You can define an interactor and increment your counter value there.
CounterInteractor:
public CounterInteractor{
public int incrementCounter(int currentCounter){
return currentCounter+1;
}
}
And refactor your presenter like below:
int totalClicks = 0;
CounterInteractor mCounterInteractor = new CounterInteractor();
public void onCounterButtonClicked(){
totalClicks = mCounterInteractor.incrementCounter(totalClicks);
mView.showCounterCount(totalClicks);
}
With this approach you separate your business logic totally from presenters and re use your use-case concepts without duplicating code in presenters. This is more clean approach.
You can also check this git repo for different MVP Approaches.

d12105 | train | Session.Abandon()
cancels the current session
Session.Clear()
will just clear the session data and the the session will remain alive
more Details:
Session.Abandon() method destroys all the objects stored in a Session object and releases their resources. If you do not call the Abandon method explicitly, the server destroys these objects when the session times out(I may add:Session_OnEnd event is triggered)

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive. | unknown | |

d12107 | train | First you must understand the index process, basically your string is passed trough the default analyser if you didn't change the default mapping.
HipHop will kept the same
Hip Hop is saved separated like Hip, Hop
When you do a match query like your example with HipHop vs Hip Hop, this query is passed trough the analyser too and will be separated like: "HipHop, vs, Hip, Hop" and a boolean query that will do a search like this: "match HipHop there?", "match vs there?", "match Hip there?", "match Hop there?" ?
If you want a scenario where you have HipHop indexed and the user search for Hip Hop or HipHop vs Hip Hop or HopHip and should return HipHop, you must implement some strategy like:
Regex or prefix query: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-regexp-query.html
Ngram for partial matching: https://www.elastic.co/guide/en/elasticsearch/guide/current/_ngrams_for_partial_matching.html
Synonyms: https://www.elastic.co/guide/en/elasticsearch/guide/current/using-synonyms.html
And if you want to keep you terms with space indexed like "Hip Hop" you need to use a not_analyzed mapping. | unknown | |
d12108 | train | if I understand you correctly, then what you are trying to do is to my knowledge not possible with gnuplot. Or at least not in an easy way. And this is the reason why I think you'll have a hard time:
You cannot plot different box widths in a single plot. So trying to plot no box on an "non eventful" day and a single column on a day with one event will work just fine. Plotting multiple columns on one day where more than one event occurs in the same plot will fail because:
*
*You cannot set different box sizes in the same plot
*You need to offset the boxes on the same day according to the amount of events
There are ways to work around that problem for example plot two boxes of the same color next to each other to "simulate" a single box on one day and then make use of the smaller box width on days with two events. But this will very soon get pretty hairy and hard to maintain.
Maybe you want to think about using a different plot style? Take a look at histograms like here. Maybe one of the styles suites your data better. Or you could think about splitting your plot up into multiple plots? | unknown | |
d12109 | train | Obviously neither the "if" nor the "else if" condition are true then. Add
let dilutiontext = self.dilution.text
let celltext = self.cell.text
then set a breakpoint and examine the values.
A: Clearly the alerts were skipped if one of the if conditions in the segue function was true. So if there was something that would initially make the statements false and then after going through the alerts it would make them true, the problem would be solved.
Therefore I made two more functions each for the if and if else statements in the segue func.
func option1() -> Bool {
if (self.number1.text?.isEmpty) ?? true || self.number2.text?.isEmpty ?? true || self.number3.text?.isEmpty ?? true || self.number4.text?.isEmpty ?? true || self.dilution.text?.isEmpty ?? true || !(self.number5.text?.isEmpty ?? true) || !(self.number6.text?.isEmpty ?? true) || !(self.number7.text?.isEmpty ?? true) || !(self.number8.text?.isEmpty ?? true) {
return false
} else {
return true
}
}
func option2() -> Bool {
if (self.number1.text?.isEmpty) ?? true || self.number2.text?.isEmpty ?? true || self.number3.text?.isEmpty ?? true || self.number4.text?.isEmpty ?? true || self.number5.text?.isEmpty ?? true || self.number6.text?.isEmpty ?? true || self.number7.text?.isEmpty ?? true || self.number8.text?.isEmpty ?? true || self.dilution.text?.isEmpty ?? true {
return false
} else {
return true
}
}
which checked if all the conditions were true and if so returned true, so that the program could move on to the segue func.
The segue would check whether the conditions were true, if not, it would go through the alerts-therefore making the option1() or option2() return true- and so the if conditions in the segue func would be true for the program to continue.
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
var vc = segue.destination as! SecondViewController
if option1() == true {
vc.n1 = Int(number1.text!)!
vc.n2 = Int(number2.text!)!
vc.n3 = Int(number3.text!)!
vc.n4 = Int(number4.text!)!
vc.dil = Int(dilution.text!)!
vc.cn = Int(choose.selectedSegmentIndex)
} else if option2() == true {
vc.n1 = Int(number1.text!)!
vc.n2 = Int(number2.text!)!
vc.n3 = Int(number3.text!)!
vc.n4 = Int(number4.text!)!

d12110 | train | Link to the docs:
http://developers.facebook.com/docs/authentication/
There are several flows, but essentially, you provide a link for the client to authenticate at facebook:
https://www.facebook.com/dialog/oauth?client_id=YOUR_APP_ID&redirect_uri=YOUR_URL&scope=publish_stream,manage_pages
After authing this redirects to a URL on your site prepared to handle the param code, which you then turn around and send back to facebook for your access_token, which you provide to fb_graph.
https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&redirect_uri=YOUR_URLclient_secret=YOUR_APP_SECRET&code=CODE
There are other permissions as well, so you might want to check the facebook docs to see if there are more you need.
Facebook uses OAuth 2 for auth, and there are several ruby gems you can use to facilitate this process slightly, including the oauth2 gem.
A: The app ID you specified must be wrong. please cross check that. A sample appID looks like this

d12116 | train | Why you are trying to bold text doing it by hand when you can use built in feature. Modern browsers implements execCommand function that allows to bold, underline etc. on text. You can write just:
$('.embolden').click(function(){
document.execCommand('bold');
});
and selected text will be made bold and if it's already bold, the text styling will be removed.
A list of commands and a little doc can be found here. (More about browser support here).
$(document).ready(function() {
$('#jBold').click(function() {
document.execCommand('bold');
});
});
#fake_textarea {

}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="jBold"><b>B</b></button>
<div id='fake_textarea' contenteditable>
Select some text and click the button to make it bold...
<br>Or write your own text
</div>
A: Copied function from this answer: Get parent element of a selected text
Haven't really perfected this and I think this only works on exact selections but it gives you an idea of how to go around this. The click function checks if the parent element of the current selection has the class 'bold', if so it replaces that element with the original selection again.
http://jsfiddle.net/XCb95/4/
jQuery(function($) {
$('.embolden').click(function(){
var highlight = window.getSelection();
var span = '<span class="bold">' + highlight + '</span>';
var text = $('.textEditor').html();
var parent = getSelectionParentElement();
if($(parent).hasClass('bold')) {
$('.textEditor').html(text.replace(span, highlight));
} else {
$('.textEditor').html(text.replace(highlight, span));
}
});
});
function getSelectionParentElement() {
var parentEl = null, sel;
if (window.getSelection) {
sel = window.getSelection();
if (sel.rangeCount) {
parentEl = sel.getRangeAt(0).commonAncestorContainer;
if (parentEl.nodeType != 1) {
parentEl = parentEl.parentNode;
}
}
} else if ( (sel = document.selection) && sel.type != "Control") {
parentEl = sel.createRange().parentElement();
}
return parentEl;
}
A: Something like this should do the trick:
var span = '';
jQuery(function($) {
$('.embolden').click(function(){
var highlight = window.getSelection();
if(highlight != ""){
span = '<span class="bold">' + highlight + '</span>';
}else{
highlight = span;
span = $('span.bold').html();
}
var text = $('.textEditor').html();
$('.textEditor').html(text.replace(highlight, span));
});
});

You'll notice that I extended the button to have a couple data- attributes. They should be rather self-explanatory.
This will also de-apply to subsections of the selected text which are within the currently-targeted element (everything goes by class name).
As you can see, I'm using a class which is a combination of things so this gives you more versatility.
A: If you are looking to use the keyboard to bold characters, you can use the following (Mac):
$(window).keydown(function(e) {
if (e.keyCode >= 65 && e.keyCode <= 90) {
var char = (e.metaKey ? '⌘-' : '') + String.fromCharCode(e.keyCode)
if(char =='⌘-B') {
document.execCommand('bold')
}
}
})
Using keyboard to bold character:
A: This code goes thru the content of the textEditor and removes all the span tags. It should do the trick.
jQuery(function($) {
$('.embolden').click(function(){
$('.textEditor span').contents().unwrap();
var highlight = window.getSelection();
var span = '<span class="bold">' + highlight + '</span>';
var text = $('.textEditor').html();
$('.textEditor').html(text.replace(highlight, span));
});
});
A: Modern browsers utilize the execCommand function that allows you to embolden text very easily. It also provides other styles like underline etc.
<a href="#" onclick="emboldenFont()">Bold</a>
function emboldenFont() {
document.execCommand('bold', false, null);
}

d12117 | train | It's not so much that PostgreSQL "preserves" indexes across subqueries, as that the rewriter can often simplify and restructure your query so that it operates on the base table directly.
In this case the query is unnecessarily complicated; the subqueries can be entirely eliminated, making this a trivial self-join.
SELECT count(*)
FROM chromosomal_positions file_1
INNER JOIN chromosomal_positions other_files
ON ( file_1.chromosome_id = other_files.chromosome_id
AND file_1.position = other_files.position )
WHERE file1.variant_file_id = 1
AND other_files.variant_file_id != 1;
so an index on (chromosome_id, position) would be clearly useful here.
You can experiment with index choices and usage as you go, using explain analyze to determine what the query planner is actually doing. For example, if I wanted to see if:
then I would
CREATE INDEX cp_f_c_p ON chromosomal_positions(file_id, chromosome_id , position);
-- Planner would prefer seqscan because there's not really any data;
-- force it to prefer other plans.
SET enable_seqscan = off;
EXPLAIN SELECT count(*)
FROM (
SELECT *
FROM chromosomal_positions
WHERE file_id = 1
) AS file_1
INNER JOIN (
SELECT *
FROM chromosomal_positions
WHERE file_id != 1
) AS other_files
ON ( file_1.chromosome_id = other_files.chromosome_id
AND file_1.position = other_files.position )
and get the result:

(11 rows)
(view on explain.depesz.com)
showing that while it will use the index, it's actually only using it for the first column. It won't use the rest, it's just filtering on file_id. So the following index is just as good, and smaller and cheaper to maintain:
CREATE INDEX cp_file_id ON chromosomal_positions(file_id);
Sure enough, if you create this index Pg will prefer it. So no, the index you propose does not appear to be useful, unless the planner thinks it's just not worth using at this data scale, and might choose to use it in a completely different plan with more data. You really have to test on the real data to be sure.
By contrast, my proposed index:
CREATE INDEX cp_ci_p ON chromosomal_positions (chromosome_id, position);
is used to find chromosomal positions with id = 1, at least on an empty dummy data set. I suspect the planner would avoid a nested loop on a bigger data set than this, though. So again, you really just have to try it and see.
(BTW, if the planner is forced to materialize a subquery then it does not "preserve indexes on derived tables", i.e. materialized subqueries. This is particularly relevant for WITH (CTE) query terms, which are always materialized). | unknown | |

Convert the exported data to another file containing UPDATE statements where you only update the newly created column with values converted from JSON to a map. For conversion use a tool or language of your choice (be it bash, python, perl or whatever).
BTW be aware, that with map you specify what data type is your map's key and what data type is your map's value. So you will most probably be limited to use strings only if you want to be generic, i.e. a map<text, text>. Consider whether this is appropriate for your use case. | unknown | |

d12127 | train | UMAP has multiple purposes like clustering, supervised learning and outlier detection.
What exactly do you want to do with UMAP?
In case of clustering, you can take a look at sklearn cluster evaluation and compare the scores with other algorithms like t-SNE.
To look for the structure, you can reduce your data to 2-3 dimensions and use a scatter plot to eye check the results.
When you have labeled data, you can try to classify them with (nonlinear) classifiers like a random forest and compare the result score (e.g. accuracy) with other dimension reduction techniques like PCA.
Maybe you look for the trustworthiness from sklearn. You can compare the scores of PCA with the score of UMAP or any other dimension reduction algorithm. source | unknown | |

d12136 | train | In my manifest permissions look like this:
<uses-permission android:name="android.permission.NFC" />
Maybe that's the problem? | unknown | |
d12137 | train | Okay, I'll try to write a complete walk-through.
First, it is a common mistake to treat WAV (or, more likely, RIFF) file as a linear structure. It is actually a tree, with each element having a 4-byte tag, 4-byte length of data and/or child elements, and some kind of data inside.
It is just common for WAV files to have only two child elements ('fmt ' and 'data'), but it also may have metadata ('LIST') with some child elements ('INAM', 'IART', 'ICMT' etc.) or some other elements. Also there's no actual order requirement for blocks, so it is incorrect to think that 'data' follows 'fmt ', because metadata may stick in between.
So let's look at the RIFF file:
'RIFF'
|-- file type ('WAVE')
|-- 'fmt '
| |-- AudioFormat
| |-- NumChannels
| |-- ...
| L＿ BitsPerSample
|-- 'LIST' (optional)
| |-- ... (other tags)
| L＿ ... (other tags)
L＿ 'data'
|-- sample 1 for channel 1
|-- ...
|-- sample 1 for channel N
|-- sample 2 for channel 1
|-- ...
|-- sample 2 for channel N
L＿ ...
So, how should you read a WAV file? Well, first you need to read 4 bytes from the beginning of the file and make sure it is RIFF or RIFX tag, otherwise it is not a valid RIFF file. The difference between RIFF and RIFX is the former uses little-endian encoding (and is supported everywhere) while the latter uses big-endian (and virtually nobody supports it). For simplicity let's assume we're dealing only with little-endian RIFF files.
Next you read the root element length (in file endianness) and following file type. If file type is not WAVE, it is not a WAV file, so you might abandon further processing. After reading the root element, you start to read all child elements and process those you're interested in.
Reading fmt header is pretty straightforward, and you have actually done it in your code.
Data samples are usually represented as 1, 2, 3 or 4 bytes (again, in the file endianness). The most common format is a so-called s16_le (you might have seen such naming in some audio processing utilities like ffmpeg), which means samples are presented as signed 16-bit integers in little endian. Other possible formats are u8 (8-bit samples are unsigned numbers!), s24_le, s32_le. Data samples are interleaved, so it is easy to seek to arbitrary position in a stream even for multi-channel audio. Note: this is valid only for uncompressed WAV files, as indicated by AudioFormat == 1. For other formats data samples may have another layout.
So let's take a look at a simple WAV reader:
stHeaderFields = dict()
rawData = None
with open("file.wav", "rb") as f:
riffTag = f.read(4)
if riffTag != 'RIFF':
print 'not a valid RIFF file'
exit(1)
riffLength = struct.unpack('<L', f.read(4))[0]
riffType = f.read(4)
if riffType != 'WAVE':
print 'not a WAV file'
exit(1)
# now read children
while f.tell() < 8 + riffLength:
tag = f.read(4)
length = struct.unpack('<L', f.read(4))[0]
if tag == 'fmt ': # format element
fmtData = f.read(length)
fmt, numChannels, sampleRate, byteRate, blockAlign, bitsPerSample = struct.unpack('<HHLLHH', fmtData)
stHeaderFields['AudioFormat'] = fmt
stHeaderFields['NumChannels'] = numChannels
stHeaderFields['SampleRate'] = sampleRate
stHeaderFields['ByteRate'] = byteRate
stHeaderFields['BlockAlign'] = blockAlign
stHeaderFields['BitsPerSample'] = bitsPerSample
elif tag == 'data': # data element
rawData = f.read(length)
else: # some other element, just skip it
f.seek(length, 1)
Now we know file format info and its sample data, so we can parse it. As it was said, sample may have any size, but for now let's assume we're dealing only with 16-bit samples:
blockAlign = stHeaderFields['BlockAlign']
numChannels = stHeaderFields['NumChannels']
# some sanity checks
assert(stHeaderFields['BitsPerSample'] == 16)
assert(numChannels * stHeaderFields['BitsPerSample'] == blockAlign * 8)
for offset in range(0, len(rawData), blockAlign):
samples = struct.unpack('<' + 'h' * numChannels, rawData[offset:offset+blockAlign])
# now samples contains a tuple with sample values for each channel
# (in case of mono audio, you'll have a tuple with just one element).
# you may store it in the array for future processing,
# change and immediately write to another stream, whatever.
So now you have all the samples in rawData, and you may access and modify it as you like. It might be handy to use Python's array() to effectively access and modify data (but it won't do in case of 24-bit audio, you'll need to write your own serialization and deserialization).
After you've done with data processing (which may involve upscaling or downscaling the number of bits per sample, changing number of channels, sound levels manipulation etc.), you just write a new RIFF header with correct data length (usually may be computed with a simplified formula 36 + len(rawData)), an altered fmt header and data stream.
Hope this helps. | unknown | |

d12141 | train | If you would start with looking at ultimate source of Unix error code names (/usr/include/errno.h) you'll arrive at the file which contains your error code as
#define EINTR 4 /* Interrupted system call */
(Which is this file is left for you to find out, as an exercise ;))
A: The errno values can be different for different systems (even different Unix-like systems), so the symbolic constants should be used in code.
The perror function will print out (to stderr ) a descriptive string of the last errno value along with a string you provide.
man 3 perror
The strerror function simply returns a const char * to the string that perror prints.
If 4 is EINTR on your system then you received a signal during your call to read. There are ways to keep this from interrupting your system calls, but often you just need to:
while (1) {
ssize_t x = read(file, buf, len);
if (x < 0) {
if (errno == EINTR) {
errno = 0;
continue;
} else {
// it's a real error
A: If you're getting EINTR, it probably means you've installed a signal handler improperly. Good unices will default to restartable system calls when you simply call signal, but for safety, you should either use the bsd_signal function if it's available, or call sigaction with the restartable flag to avoid the headaches of EINTR. | unknown | |
d12142 | train | http://psacake.com/web/jr.asp contains full instructions, and here's an excerpt:
While it may seem odd to think about purposefully causing a Blue Screen Of Death (BSOD), Microsoft includes such a provision in Windows XP. This might come in handy for testing and troubleshooting your Startup And Recovery settings, Event logging, and for demonstration purposes.
Here's how to create a BSOD:
Launch the Registry Editor (Regedit.exe).
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters.
Go to Edit, select New | DWORD Value and name the new value CrashOnCtrlScroll.
Double-click the CrashOnCtrlScroll DWORD Value, type 1 in the Value Data textbox, and click OK.
Close the Registry Editor and restart Windows XP.
When you want to cause a BSOD, press and hold down the [Ctrl] key on the right side of your keyboard, and then tap the [ScrollLock] key twice. Now you should see the BSOD.
If your system reboots instead of displaying the BSOD, you'll have to disable the Automatically
Restart setting in the System Properties dialog box. To do so, follow these steps:
Press [Windows]-Break.
Select the Advanced tab.
Click the Settings button in the Startup And Recovery panel.
Clear the Automatically Restart check box in the System Failure panel.
Click OK twice.
Here's how you remove the BSOD configuration:
Launch the Registry Editor (Regedit.exe).
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters.
Select the CrashOnCtrlScroll value, pull down the Edit menu, and select the Delete command.
Close the Registry Editor and restart Windows XP.
Note: Editing the registry is risky, so make sure you have a verified backup before making any changes.
And I may be wrong in assuming you want BSOD, so this is a Microsoft Page showing how to capture kernel dumps:
https://web.archive.org/web/20151014034039/https://support.microsoft.com/fr-ma/kb/316450
A: As far as I know, the "Create Dump" command was only added to Task Manager in Vista. The only process I know of to do this is using the adplus VBScript that comes with Debugging Tools. Short of hooking into dbghelp and programmatically doing it yourself.
A: You can setup the user dump tool from Microsoft with hot keys to dump a process. However, this is a user process dump, not a kernel dump...

d12143 | train | From what I can deduce by looking at the code given, first you are loading the data into the list dataList and then you are reversing the entire list using Collections.reverse(dataList); which is an expensive operation.
So, a way around is make your own reversing function to reverse the arraylist because the default .reverse() provided by the Collections class is not very efficient.
You can try the below code to reverse the list in-place (same ArrayList is used ,hence making it efficient):
public ArrayList<Integer> revArrayList(ArrayList<Integer> list)
{
for (int i = 0; i < list.size() / 2; i++) {
Integer temp = list.get(i);
list.set(i, list.get(list.size() - i - 1));

*It's possible to store images in a database file, usually as binary blobs (which look like instances of NSData in Core Data). If you can provide more info about your model or the code that stores/loads the images, we can be more specific.
*"Creating new store" is expected to get logged every time the app is launched in this instance. Even though the SQLite file is persistent on disk, you can't expect data structures in your code to stick around when your app is terminated - you need to create a new persistent store object for your program every time it launches.
Think of it like assigning NSInteger x = 10, then expecting to be able to quit and relaunch your program while maintaining that x has the value 10. That's not how programs work - you'd need to reassign x = 10 before you can expect to read x and get 10 back. The variable _persistentStoreCoordinator works the same way here. | unknown | |

downloader.Concurrency = 1
Therefore you can take an io.Writer and wrap it to fulfill the io.WriterAt, throwing away the offset that you no longer need:
type FakeWriterAt struct {
w io.Writer
}
func (fw FakeWriterAt) WriteAt(p []byte, offset int64) (n int, err error) {
// ignore 'offset' because we forced sequential downloads
return fw.w.Write(p)
}
A: I was looking for a simple way to get io.ReadCloser directly from an S3 object. There is no need to buffer response nor reduce concurrency.
import "github.com/aws/aws-sdk-go/service/s3"
[...]
obj, err := c.s3.GetObject(&s3.GetObjectInput{
Bucket: aws.String("my-bucket"),
Key: aws.String("path/to/the/object"),
})
if err != nil {
return nil, err
}
// obj.Body is a ReadCloser
return obj.Body, nil
A: With aws-sdk-go-v2, the codebase-provided example shows:
// Example:
// pre-allocate in memory buffer, where headObject type is *s3.HeadObjectOutput
buf := make([]byte, int(headObject.ContentLength))
// wrap with aws.WriteAtBuffer
w := s3manager.NewWriteAtBuffer(buf)
// download file into the memory
numBytesDownloaded, err := downloader.Download(ctx, w, &s3.GetObjectInput{
Bucket: aws.String(bucket),
Key: aws.String(item),
})
Then use w.Bytes() as the result.

d12153 | train | It is not possible to have a fully fledged nested function definition in VB.NET. The language does support multi-line lambda expressions which look a lot like nested functions:
Private Sub button1_Click(sender As Object, e As EventArgs) Handles button1.Click
Dim anim =
Sub()
Me.Refresh()
...
End Sub
End Sub
There are some notable differences though:
*
*Cannot have a Handles clause.
*Cannot be Implements or Overrides.
*The instance of the lambda is named, not the Sub definition.
*In this case anim is actually a delegate and not a function.
A: It is possible to have a function within a function, called lambda expressions.
In your case, however, it is unclear to me how it can be useful.

d12154 | train | I prefer to draw into Bitmaps with System.Drawing.Graphics object.
Then you can use your graphics object with "go.DrawImage(...)" to draw the bitmap directly into your winforms and actually give it a scale.
https://msdn.microsoft.com/en-us//library/ms142040(v=vs.110).aspx

A: You can use transformations for that. The graphics object you use for painting things has a Transformation property of type System.Drawing.Drawing2D.Matrix.
Graphics also has the ScaleTransform method.

d12156 | train | You can use the session for this purspose.
def open
@ticket = Ticket.find(params[:ticket_id])
@ticket.update_attributes(:ticket_status, "closed")
session[:close_message] = "Ticket has been closed"
redirect_to ticket_path
end
After that diaplay it in the view like
<%= session[:close_message] %>
but make sure to clear the session like session[:close_message] = nil after displaying the message to free the memory
A: You need to store the message in database if you want it to persist. Say for ex- There is a ticket raised (Ticket model) and someone closes it. The attribute on backend will update attribute status for ticket model.
def update
tkt = Ticket.where(id: 1)
tkt.update_attributes(status: 1)
end
If this is an ajax call, you can send a response data with message like "Ticket closed " and display it accordingly on html page in the success callback of ajax call. If it's a server call, refresh the page and use the status attribute from Ticket model to create the message.
You can use some enums like
{0 => "Ticket Open", 1 => "Ticket closed", 2 => "Ticket in progress" }
In case messages are not generic and every time some more customization is required, better to create and save the entire message as an attribute in the related model and no need to have enums. | unknown | |
d12157 | train | At the first you try add role to member id, not a member. If no members mention in message, you will get empty mention collection and try get id of undefined, because message.mentions.members.first() of empty collection return undefined.
Second, try not use role names, use role ID for this, its more secure. And change your if code from if (statment) then do something to if (!statment) return reject reason this will help avoid unnecessary nesting of code.
module.exports = {
name: 'mute',
description: 'command to mute members',
execute(message, args){

d12158 | train | You won't be able to use SimRing (Dial Verb with Multiple Nested Number nouns) with that approach, as the first person to pick up the call results in all the other call legs being cancelled.
You will need to use the /Calls resource to initiate the calls, and return TwiML that asked the dialed party to press any digit to be connected to the customer. You would then cancel (status=canceled) the other call legs. As you can see SimRing is not the best approach as it tends to tire out the dialed parties with incessant ringing and the voicemail issues you need to guard against as well as the default Calls Per Second (CPS) is 1 per second, so there will be a delay between each outbound call, unless you have Twilio Sales increase the outbound CPS.
Once the agent presses a key, you can initiate a Dial Number to the customer. If you need to modify the call once it is established, you should connect the agent to a conference and the customer to the same conference, you anchors the call legs and allows easier manipulation of the call. | unknown | |

d12160 | train | One possibility is to poll the results page. When it doesn't return a 404, you load the page. This answer by KyleMit to another question should work in your situation. To adapt his code:
const poll = async function (fn, fnCondition, ms) {
let result = await fn();
while (fnCondition(result)) {
await wait(ms);
result = await fn();
}
return result;
};
const wait = function (ms = 1000) {
return new Promise(resolve => {
setTimeout(resolve, ms);
});
};
(async() => {
const url = "/result.html";
let fetchResult = () => fetch(url);
let validate = result => !result.ok;
let response = await poll(fetchResult, validate, 3000);
if (response.ok)
location.replace(url);
})();
Disadvantages of this approach are:
*
*Polling increases network traffic
*You load the page twice.
The advantage is that you can make the results page a parameter, then the user can close the page then come back later and continue waiting. | unknown | |
d12161 | train | Yes, you can use use multiple layouts in single XML using the <include>.

A: Not sure whether your looking for this alignment but i just gave a shot..... whenever you wish to fix layout at the bottom of screen make sure you use weight property i.e if you want fix button at the bottom of screen then put android:layout_height = "0dp" and layout_weight="1" for other major layout in the xml and to button which has to be fixed at the bottom use android:layout_height="wrap_content" and layout_weight = "0" that's all is the trick (sorry if i have made it hard to understand... just simply saying play with weight and height property)

d12163 | train | Does ChildClassA also contain a collection, thus you are trying to nest two embedded collections? It looks like it from that stacktrace. This is not possible in Objectify4. I highly recommend the upgrade to 5. | unknown | |
d12164 | train | am I crazy or will never work under any circumstance?
Q) Are you crazy?
A) Yes. Absolutely. That looks bonkers!
Q) Will this never work under any circumstance?
A) Oh, there are times this will work. Some observables are synchronous.
For example, this will always log a 2, so this works as expected.
let convertedView = null;
of(1).pipe(
map(v => v + 1)
).subscribe(convertedOrder => convertedView = convertedOrder);
console.log(convertedView);
That's because of(1) is a synchronous observable.
This, however, will never work
let convertedView = null;
of(1).pipe(
delay(0),
map(v => v + 1)
).subscribe(convertedOrder => convertedView = convertedOrder);
console.log(convertedView);
This will print null. Even though delay(0) conceptually takes no time, it still uses JSs event loop and therefore doesn't get executed until the current code completes.
I think it's best practise to assume all observables are asynchronous. Any code that assume otherwise is likely to be brittle.
A: Your store.subscribe is asynchronous and the rest of your code is not.
You can resolve it with a Promise like the example below.
protected get reportView(): Promise < any > {
return new Promise((resolve, reject) => {
this.store
.pipe(select(fromStore.getTransferOrderConverted), rxjs.take(1))
.subscribe((convertedOrder) => resolve(convertedOrder));
});
}
reportView.then(convertedOrder => {
// do your stuff
});
Also you can get the convertedOrder with Async/Await. But remember, the parent function must be async.
const convertedOrder = await reportView();
A: Convert a stream to synchronous isn't a good ideal.
However, you can use method toPromise of a subject (subscription) for convert it to a promise and await for resolve.
A: Rxjs take(1), first() operator should work absolutely fine
These 2 operators takes the latest value from store selector or BehaviourSubject in synchronous way. | unknown | |

d12166 | train | You definitely should use a php framework !
It will help you to organize your code and will bring to you some helpful features like routing which would solve your problem.
You will define some roots, each linked to a specific controller and your code will be well organized.
I can recommend you Symfony2 :
but there are a lot of which are able to do the job :
http://www.hongkiat.com/blog/best-php-frameworks/
If your application is small you can have a look to silex which is a light version of Symfony
To define your urls, you can use a REST api which is a best practice.

d12168 | train | I guess you mean the html select box having some page titles displayed and as soon as the user selects one of them the new page showes up.
This is not possible with out javascript - the only thing you could do is to add a submit button.
<noscript><input type="submit" value="go!"></noscript>
This button would only be displayed if javascript is not activated.
A: No, you cannot reload a page when a select box changes (if that's your question) without using a scripting language or similar.
A: Without a scripting language (that would be JavaScript if you want to be cross-browser), most form elements are "dumb", they hold their state and display user feedback.
So if you want to select a new page after selecting it in a form (combo box, list, radio buttons...), you have to add a submit button to send the choice to a server, and have a server side script handling the choice and serving the right page.
The good old Web 1.0 way... :-)
A: You can't. With HTML only, changing the selected option makes the value of that option to be sent to the server upon submit (either via the Enter key or a submit/button element). You can eventually set up the receiving script to send back a HTTP Redirect based according to the selected option.
You shouldn't. This kind of navigation widget implies the use of a mouse: somebody using the keyboard to navigate the page cannot even select the second option at all (as soon as the down arrow is pressed once the onchange() event activates). Do the right thing and add a submit button, with the page change activated by the onsubmit() event. | unknown | |
d12169 | train | Windows line endings consist of two separate characters, a carriage return ('\r') immediately followed by a newline ('\n'). Because they are a combination of two characters, you cannot detect them by looking at only one character at a time.
If your code is running on Windows and the file is supposed to be interpreted as text, then open it in text mode (for instance, "r" instead of "rb"), and the line terminators should be automatically translated to single newlines. If you're running on a system that uses single newlines as line terminators (most anything but Windows these days) then no such translation will be performed. In that case, to detect Windows-style line terminators you need to keep track of whether the immediately previous character was a '\r'. When that is so, and the next character read is a '\n', then you've detected a line terminator.
But if it should be considered erroneous for Windows-style terminators to be in the file, then consider instead just fixing the file via dos2unix or a similar utility. | unknown | |
d12170 | train | That's not a prompt, it's just a message.
Prompting would be:
read -p "Please pass a grade: " gr
But this get's into conflict with your following gr=$1, so put this into an else block:
if [ $# -lt 1 ]
then
read -p "Please pass a grade: " gr
else
gr=$1
fi
Note that you don't need a semicolon at the line end; it's the line break, which can be substituted by the semicolon.
And you don't need an exit to end a script, if you don't want to exit prematurely.
A: As you want to prompt the user to input grades until he enters 999, you should use read instead of command line arguments. As bash doesn't have a do-while loop, we can emulate it's behavior using while as shown below:
#!/bin/bash
read -p "Please pass a grade " gr
while [ $gr -ne 999 ]; do
if [ $gr -ge 90 ]

d12171 | train | Outlook does not expose events that will allow you to expand or collapse the folders in the treeview. You may be able to do this using the Windows API.
A: There might be a way to expand (but not to collapse).
Basically what you need to do is to go through your sub folders one by one during each step make the sub folder your current folder.
I have tested this in Outlook 2010 (VSTO) on addin startup. So if you have the Parent Folder Folder A and its sub folders Folder A1, Folder A2 and Folder A3.
In order to expand Folder A do the following:
*
*Get the active explorer (Globals.thisaddin.application.activeexplorer)
*Set the current folder explorer.currentfolder = Folder A
*Now loop through all sub folders under Folder A and make each sub folder the current folder:
(The code should be something like this)
Subfolders = FolderA.Folders
For Each folder as outlook .folder in Subfolders
Explorer.currentfolder = folder
Next Folder
This method works for me so hope this would be hopeful | unknown | |
d12172 | train | In short, you can't. map3 doesn't have the correct types to merge map1 and map2 into it.
However if it was also a HashMap<String, List<Incident>>. You could use the putAll method.
map3 = new HashMap<String, List<Incident>>();
map3.putAll(map1);
map3.putAll(map2);
If you wanted to merge the lists inside the HashMap. You could instead do this.
map3 = new HashMap<String, List<Incident>>();
map3.putAll(map1);
for(String key : map2.keySet()) {
List<Incident> list2 = map2.get(key);
List<Incident> list3 = map3.get(key);
if(list3 != null) {
list3.addAll(list2);
} else {
map3.put(key,list2);

A: create third map and use putAll() method to add data from ma
HashMap<String, Integer> map1 = new HashMap<String, Integer>();
HashMap<String, Integer> map2 = new HashMap<String, Integer>();
HashMap<String, Integer> map3 = new HashMap<String, Integer>();
map3.putAll(map1);
map3.putAll(map2);
You have different type in question for map3 if that is not by mistake then you need to iterate through both map using EntrySet
A: Use commons collections:
Map<String, List<Incident>> combined = CollectionUtils.union(map1, map2);
If you want an Integer map, I suppose you could apply the .hashCode method to all values in your Map.
A: HashMap has a putAll method.

I test it in my side with batchSize as 1 and set functionAppScaleLimit to 2(I set WEBSITE_MAX_DYNAMIC_APPLICATION_SCALE_OUT as 2 in "Application settings" of function app instead of set functionAppScaleLimit, they are same). And I test with the code below:
import logging
import azure.functions as func
import time
def main(msg: func.QueueMessage) -> None:
logging.info('=========sleep start')
time.sleep(30)
logging.info('=========sleep end')
logging.info('Python queue trigger function processed a queue item: %s',
msg.get_body().decode('utf-8'))
Then I add message to the queue, I sent 10 messages: 111, 222, 333, 444, 555, 666, 777, 888, 999, 000, I sent them one by one. The function was triggered success and after a few minutes, we can see the logs in "Monitor". Click one of the log in "Monitor", we can see the logs show as:
I use 4 red boxes on the right of the screenshot above, I named each of the four logs as "s1", "s2", "s3", "s4"(step 1-4). And summarize the logs in excel for your reference:
I make cells from "s2" to "s4" as yellow because this period of time refer to the execution time of the function task.
According the screenshot of excel, we can infer the following points:
1. The maximum number of instances can only be extended to 2 because we can find it doesn't exist more than two yellow cells in each line of the excel table. So the function can not scale beyond 2 instances as you mentioned in your question.
2. You want to allow both of these queue triggers to run concurrently, it can be implemented. But the instances will be scale out by mechanism of consumption. In simple terms, when one function instance be triggered by one message and hasn't completed the task, and now another message come in, it can not ensure another instance be used. The second message might be waiting on the first instance. We can not control whether another instance is enabled or not.
===============================Update==============================
As I'm not so clear about your description, I'm not sure how many storage queues you want to listen to and how many function apps and QueueTrigger functions you created in your side. I summarize my test result as below for your reference:
1. For your question about would the Maximum Burst you described on the premium plan behave differently than this ? I think if we choose premium plan, the instances will also be scale out with same mechanism of consumption plan.
2. If you have two storage queues need to be listen to, of course we should create two QueueTrigger functions to listen to each storage queue.
3. If you just have one storage queue need to be listen to, I test with three cases(I set max scale instances as 2 in all of three cases):
A) Create one QueueTrigger function in one function app to listen to one storage queue. This is what I test in my original answer, the excel table shows us the instances will scale out by mechanism of consumption plan and we can not control it.
B) Create two QueueTrigger functions in one function app to listen to same storage queue. The result is almost same with case A, we can not control how many instances be used to deal with the messages.
C) Create two function apps and create a QueueTrigger function in each of function app to listen to same storage queue. The result also similar to case A and B, the difference is the max instances can be scaled to 4 because I created two function apps(both of them can scale to 2 instances).
So in a word, I think all of the three cases are similar. Although we choose case 3, create two function apps with one QueueTrigger function in each of them. We also can not make sure the second message be deal with immediately, it still may be processed to first instance and wait for frist instance complete deal with the first message.
So the answer for your current question in this post is setting the functionAppScaleLimit to 2 enough to achieve that? is: If you want both of instances be enabled to run concurrently, we can't make sure of it. If you just want two instances to deal with the messages, the answer is yes. | unknown | |

d12177 | train | You risk printing out and comparing garbage since you don't ensure the strings are nul terminated.
You need to do
fread(file_md5, 1, md5_length, md5_fd);
file_md5[md5_length] = 0;
And similar for input_md5. Or to do it properly, use the return value of fread() to add the nul terminator in the proper place, check if fread() fails, Check how much it returned.
If you also place your debug output inside quotes, it'll also be easier to spot unwanted whitespace or unprintable characters:
fprintf(stdout, "contains '%s'\n", input_md5); | unknown | |

d12179 | train | Neither of these expressions are legal, they should both fail to compile.
C++11, 5.17.1:
The assignment operator (=) and the compound assignment operators all group right-to-left. All require a modifiable lvalue as their left operand and return an lvalue referring to the left operand.
5.4:
Explicit type conversion (cast notation) [expr.cast]
1 The result of the expression (T) cast-expression is of type T. The result is an lvalue if T is an lvalue reference type or an rvalue reference to function type and an xvalue if T is an rvalue reference to object type; otherwise the result is a prvalue.
So both expressions violate these constraints.
A:
shouldn't (long *) p be a rvalue?
It is.
They're both prvalues and, as such, both statements are ill-formed:
[C++03: 5.4/1]: The result of the expression (T) cast-expression is of type T. The result is an lvalue if T is a reference type, otherwise the result is an rvalue.
[C++11: 5.4/1]: The result of the expression (T) cast-expression is of type T. The result is an lvalue if T is an lvalue reference type or an rvalue reference to function type and an xvalue if T is an rvalue reference to object type; otherwise the result is a prvalue. [..]
GCC 4.8 rejects your "legal cast", but Visual Studio has an extension that accepts this (for no apparent reason).
A: Why do you think your cast is legal? I'm getting error C2106: '=' : left operand must be l-value on both casts.
This shouldn't be legal. If you really want to do it, you have to cast it like this:
(long*&)p = &l; // equivalent to *(long**)&p = &l
But don't do that unless you know what you are doing.
A: The result of a value conversion is an rvalue. You cannot assign to rvalues of fundamental types.
In other words, for int a = 10;, a is an lvalue of type int, but (long) a is a temporary rvalue of type long, and you cannot assign to the temporary. Likewise for pointers. | unknown | |
d12180 | train | It's a fairly easy change on a perl file to make this happen. I would only recommend doing this if you don't like the default git-add -p behavior of patching all files.
Find your copy of git-add--interactive and open with your favorite editor. Go to the patch_update_cmd subroutine. In there, there is an if statement which tests $patch_mode. Remove the top part of the if statement or set it so that the conditional always evaluates to false. Save and test.
An example of what I did to make this work follows.
if (0) {
@them = @mods;
}
else {
@them = list_and_choose({ PROMPT => 'Patch update',
HEADER => $status_head, },
@mods);
}
Another possible point of change would be at the very bottom of the file. You can change $patch_mode to some false value after the if statement, the effect should be the same.
Note you may have some issues if you're using a package manager or something else similar which tracks installed packages, I'm not sure.
A: What you could do, is 'git add -p' and add the filenames as commandline arguments.
with good tab completion (which only completes dirty files) it's about as effective as picking them from the menu.
A: If you don't mind bringing up a gui, just use git gui. | unknown | |

d12184 | train | Try using an external plugin to parse your dates, something like Datejs
A: Frankly, I'm surprised other browsers parse the string correctly, as the string you give to the date object is 1:00 AM1/20/2012. Put the date first and add a space in between.
var timeIn = new Date($('#dateIn').val() + ' ' + $('#timeIn').val());
var timeOut = new Date($('#dateOut').val() + ' ' + $('#timeOut').val());
http://jsfiddle.net/mq72k/8/
A: Javascript does not parse string dates very well at all, including ISO8601 formats. You must parse the string yourself. You especially should not expect a minor format like month/day/year to be parsed since it is used by a small minority of the global population.
Incidentally, this has nothing to do with jQuery.
Edit
To reliably parse m/d/y format:
function toDate(ds) {
var a = ds.split('/');
return new Date(+a[2], (a[0] - 1), +a[1]);
}
The above assumes a correct date string is supplied. To check that it's a valid date at the same time:
function toDate(ds) {
var a = ds.split('/');
var d = new Date(+a[2], (a[0] - 1), +a[1]);
if (d.getDate() == a[1] && d.getFullYear() == a[2]) {
return d;
} else {
return NaN; // or some other suitable value like null or undefined
}

d12185 | train | Try utilizing .each() , where i is index of element within collection , el is element , el.value is value of input type="range" current element within loop
$("input[type=range]").each(function(i, el) {
console.log(el.value);
});
https://jsfiddle.net/f3x5jfjg/15/
A: Yes, that can be done. You would have to take advantage of the change event, not the click event though.
As the ranges are wide, and it's hard to find a match I have set a match by default and used addClass() and removeClass() instead of hide() and show() just to demonstrate how to approach this. Pick any other match, if you can find one, and set your ranges to it.
$(document).ready(function () {
var ranges = $('div.box > input[type=range]'),
table = $('table.table'),
hrow = $('tr:has(th)', table),
orow = $('tr:has(td)', table);
ranges.on('change', function() {
//init range object
var orange = [];
//determine value setting & index for each range
ranges.each(function() {
var thisrange = {};
thisrange.value = this.value;
thisrange.label = $(this).prev('label').text().trim();
thisrange.column = $.inArray( thisrange.label, $('th',hrow).map(function(i,v) {
return $(v).text().trim();
}) );
$(this).next('label').text( this.value );
orange.push( thisrange );
});
//hide [remove hightlight] all rows but header
orow.removeClass('highlight');
//show [hightlight] rows with values
orow.filter(function() {
var result = true,that = this;
$.each( orange, function(i,v) {
result = result && $('td',that).eq(v.column).text().trim() == v.value;
});
return result;
}).addClass('highlight');
}).change();
});
DEMO
NOTE: Some values in the filter columns are non-numeric and would never be set on the range! And some numeric values are out of range.
Update
Here is a version that will filter just by the changed range. When the page loads it filters by the value of the first range.
$(document).ready(function () {
var ranges = $('div.box > input[type=range]'),
table = $('table.table'),
hrow = $('tr:has(th)', table),
orow = $('tr:has(td)', table);
ranges.on('change', function() {
var value = this.value,
label = $(this).prev('label').text().trim(),
column = $.inArray( label, $('th',hrow).map(function(i,v) {
return $(v).text().trim();
}) );
//display the new value
$(this).next('label').text( value );
//hide [remove hightlight] all rows but header
orow.removeClass('highlight');
//show [hightlight] rows with values
orow.filter(function() {
return $('td',this).eq(column).text().trim() == value;
}).addClass('highlight');
}).eq(0).change();

d12188 | train | Use this, it ignores onComplete() and onError(): https://github.com/JakeWharton/RxRelay | unknown | |
d12189 | train | It is because mod_rewrite runs in a loop. First rule is doing this:
Starting URL:
/searchEngine/test
Ending URL:
/searchEngine/view/index.php
Now L flag causes mod_rewrite to loop again. So now your starting URL becomes:
Starting URL:
/searchEngine/view/index.php
Now 1st rule' pattern ^test doesn't match but your 2nd rule is using .* as matching pattern hence redirects to google.
You can have your rules as follows to prevent this behavior:
RewriteEngine On
RewriteRule ^/?test$ view/index.php [NC,L]
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^ http://google.com [R,L]
2nd rule has this additional condition:
RewriteCond %{ENV:REDIRECT_STATUS} ^$
REDIRECT_STATUS is set to 200 after first rule's execution. So 2nd rule will redirect only if first rule hasn't executed first hence it will skip /test.
If you're using Apache 2.4+ then you can use END instead of L to end the execution:
RewriteEngine On
RewriteRule ^/?test$ view/index.php [NC,END]
RewriteRule ^ http://google.com [R,L]
A: This is happening because of the internal redirection, You can use the END flag instead of L to stop this behaviour :
RewriteEngine On
RewriteRule ^\/?test$ view/index.php [NC,END]
RewriteRule ^(.*)$ http://google.com [NC,L] | unknown | |
d12190 | train | Because HTTP protocol contains not only the IP address, but also the hostname (the URL you type into your browser), which differs between the <cloud_hostname> and localhost.

d12197 | train | Rust's .find passes the callback the type &Self::Item, and since you are using .iter_mut(), you've created an iterator where each item is &mut T. That means the type passed to your find callback is &&mut T. To get that to typecheck, you can do either
vec.iter_mut().find(|&&mut c| c == 2)
or
vec.iter_mut().find(|c| **c == 2)
with the second one being preferable.
The error you are getting is because the middle-ground you've chosen by using &c would set c to a value of &mut T, and one of Rust's big rules is that multiple things can't own a mutable reference to an item at the same time. Your non-mutable case works because you are allowed to have multiple immutable references to an item. | unknown | |

You can break a line at an operator, list separator, or period.
A: In VBA (and VB.NET) the line terminator (carriage return) is used to signal the end of a statement. To break long statements into several lines, you need to
Use the line-continuation character, which is an underscore (_), at the point at which you want the line to break. The underscore must be immediately preceded by a space and immediately followed by a line terminator (carriage return).
(From How to: Break and Combine Statements in Code)
In other words: Whenever the interpreter encounters the sequence <space>_<line terminator>, it is ignored and parsing continues on the next line. Note, that even when ignored, the line continuation still acts as a token separator, so it cannot be used in the middle of a variable name, for example. You also cannot continue a comment by using a line-continuation character.
To break the statement in your question into several lines you could do the following:
U_matrix(i, j, n + 1) = _
k * b_xyt(xi, yi, tn) / (4 * hx * hy) * U_matrix(i + 1, j + 1, n) + _
(k * (a_xyt(xi, yi, tn) / hx ^ 2 + d_xyt(xi, yi, tn) / (2 * hx)))
(Leading whitespaces are ignored.)
A: To have newline in code you use _
Example:
Dim a As Integer
a = 500 _
+ 80 _
+ 90

d12200 | train | The solution is simple: you have the wrong argument order in this line:
map.put(tempMap,parts[0]);
it should say
map.put(parts[0],tempMap);
You must change the type parameters of your variable declaration accordingly. Where you have
Map<Map<String,String>,String> map = new HashMap<>();
you must put
Map<String,Map<String,String>> map = new HashMap<>();
Altogether, after these changes I believe you will have the structure you really want to have: a map from parts[0] to the map of the rest of the record fields.
I should add that your solution (in addition to your nick :) gives you away as a developer who primarily codes in a dynamic language like Groovy; this style is not a good match for Java's language features. In Java you'd be better off defining a specialized bean class:
public class CardHolder {
public final String cardNumber, issuingBank, cardSwitch, cardType;
public CardHolder(String[] record) {
int i = 0;
cardNumber = record[i++];
issuingBank = record[i++];
cardSwitch = record[i++];
cardType = record[i++];
}
}
First, this approach is nicer since your reading loop becomes simpler and more to the point:
while ((sCurrentLine = br.readLine()) != null) {
final CardHolder ch = new CardHolder(sCurrentLine.split(","));
map.put(ch.cardNumber, ch);
}
Also this will allow you finer control over other aspects of your record; for example a nice custom toString and similar. Note also that this has hardly resulted in more code: it just got reorganized by the separation-of-concerns principle.
(A minor observation at the end: in Java the s-prefix to String variables is not customary because it is redundant in statically-typed languages; rest assured that you will never encounter a bug in Java due to an Integer occuring where a String was expected.)
A: You should change, how you have created your Map.. In place of your below declaration: -
Map<Map<String,String>,String> map = new HashMap<>();
Rather than this, you should have a : -
Map<String, Map<String,String>> map = new HashMap<>();
You should always have an immutable type as a key in your Map..
And after this change, you should change: -
map.put(tempMap,parts[0]);
to: -
map.put(parts[0], tempMap);
A: I think you have the arguments in
map.put(tempMap,parts[0]);
reversed. You are mapping tempMap to the number, where you probably want to be mapping the number to tempMap:
map.put(parts[0], tempMap);
Using
Map<String, Map<String,String>> map = new HashMap<>();
A: You should use Map as value since HashMap equality is based on key value pairs it has..
map.put(parts[0],tempMap);
A simple program below will illustrate this fact
Map<String, String> tempMap1 = new HashMap<String, String>();
tempMap1.put("issuing_bank", "ICICI");
tempMap1.put("card_switch", "Visa");
tempMap1.put("card_Type", "Debit");
Map<String, String> tempMap2 = new HashMap<String, String>();
tempMap2.put("issuing_bank", "ICICI");
tempMap2.put("card_switch", "Visa");
tempMap2.put("card_Type", "Debit");
System.out.println(tempMap1.equals(tempMap2));//Prints true
Output:
true
So your declaration should like below. Remember you should always use immutable object as key in HashMap.
Map<String,Map<String,String>> map = new HashMap<String,Map<String,String>>();
A: That's because you're using a map (the tempMap) as a key.
This is wrong. | unknown |
