the application must stop all regular processing when this
method is invoked, since the document is no longer reliable, and
the parser may no longer report parsing events.</p>

DOM Level 1 did not have a standard mechanism for creating a new
Document object. This function provides a DOM-implementation-independent
abstraction for that for that concept. It's typically used when
outputting a new DOM as the result of an operation.
<p>
TODO: This isn't directly compatable with DOM Level 2.
The Level 2 createDocument call also creates the root
element, and thus requires that you know what that element will be
before creating the Document. We should think about whether we want
to change this code, and the callers, so we can use the DOM's own
method. (It's also possible that DOM Level 3 may relax this
sequence, but you may give up some intelligence in the DOM by
doing so; the intent was that knowing the document type and root
element might let the DOM automatically switch to a specialized
subclass for particular kinds of documents.)

public String getUniqueID(Node node)
{
return "N" + Integer.toHexString(node.hashCode()).toUpperCase();
} |
Supports the XPath function GenerateID by returning a unique
identifier string for any given DOM Node.
<p>
Warning: The base implementation uses the Node object's hashCode(),
which is NOT guaranteed to be unique. If that method hasn't been
overridden in this DOM ipmlementation, most Java implementions will
derive it from the object's address and should be OK... but if
your DOM uses a different definition of hashCode (eg hashing the
contents of the subtree), or if your DOM may have multiple objects
that represent a single Node in the data structure (eg via proxying),
you may need to find another way to assign a unique identifier.
<p>
Also, be aware that if nodes are destroyed and recreated, there is
an open issue regarding whether an ID may be reused. Currently
we're assuming that the input document is stable for the duration
of the XPath/XSLT operation, so this shouldn't arise in this context.
<p>
(DOM Level 3 is investigating providing a unique node "key", but
that won't help Level 1 and Level 2 implementations.)
@param node whose identifier you want to obtain
@return a string which should be different for every Node object.

Obtain the XPath-model parent of a DOM node -- ownerElement for Attrs,
parent for other nodes.
<p>
Background: The DOM believes that you must be your Parent's
Child, and thus Attrs don't have parents. XPath said that Attrs
do have their owning Element as their parent. This function
bridges the difference, either by using the DOM Level 2 ownerElement
function or by using a "silly and expensive function" in Level 1
DOMs.
<p>
(There's some discussion of future DOMs generalizing ownerElement
into ownerNode and making it work on all types of nodes. This
still wouldn't help the users of Level 1 or Level 2 DOMs)
<p>
@param node Node whose XPath parent we want to obtain
@return the parent of the node, or the ownerElement if it's an
Attr node, or null if the node is an orphan.
@throws RuntimeException if the Document has no root element.
This can't arise if the Document was created
via the DOM Level 2 factory methods, but is possible if other
mechanisms were used to obtain it

Given an ID, return the element. This can work only if the document

The getUnparsedEntityURI function returns the URI of the unparsed
entity with the specified name in the same document as the context
node (see [3.3 Unparsed Entities]). It returns the empty string if
there is no such entity.
<p>
XML processors may choose to use the System Identifier (if one
is provided) to resolve the entity, rather than the URI in the
Public Identifier. The details are dependent on the processor, and
we would have to support some form of plug-in resolver to handle
this properly. Currently, we simply return the System Identifier if
present, and hope that it a usable URI or that our caller can
map it to one.
TODO: Resolve Public Identifiers... or consider changing function name.
<p>
If we find a relative URI
reference, XML expects it to be resolved in terms of the base URI
of the document. The DOM doesn't do that for us, and it isn't
entirely clear whether that should be done here; currently that's
pushed up to a higher levelof our application. (Note that DOM Level
1 didn't store the document's base URI.)
TODO: Consider resolving Relative URIs.
<p>
(The DOM's statement that "An XML processor may choose to
completely expand entities before the structure model is passed
to the DOM" refers only to parsed entities, not unparsed, and hence
doesn't affect this function.)
@param name A string containing the Entity Name of the unparsed
entity.
@param doc Document node for the document to be searched.

Support for getParentOfNode; walks a DOM tree until it finds
the Element which owns the Attr. This is hugely expensive, and
if at all possible you should use the DOM Level 2 Attr.ownerElement()
method instead.
<p>
The DOM Level 1 developers expected that folks would keep track
of the last Element they'd seen and could recover the info from
that source. Obviously that doesn't work very well if the only
information you've been presented with is the Attr. The DOM Level 2
getOwnerElement() method fixes that, but only for Level 2 and
later DOMs.

Create a new dispatcher from a stream.
@param stream
The stream to read data from.
@param audioBufferSize
The size of the buffer defines how much samples are processed
in one step. Common values are 1024,2048.
@param bufferOverlap
How much consecutive buffers overlap (in samples). Half of the
AudioBufferSize is common (512, 1024) for an FFT.

Set a new step size and overlap size. Both in number of samples. Watch
out with this method: it should be called after a batch of samples is
processed, not during.
@param audioBufferSize
The size of the buffer defines how much samples are processed
in one step. Common values are 1024,2048.
@param bufferOverlap
How much consecutive buffers overlap (in samples). Half of the
AudioBufferSize is common (512, 1024) for an FFT.

public void setZeroPadFirstBuffer(boolean zeroPadFirstBuffer){

} |
if zero pad is true then the first buffer is only filled up to buffer size - hop size
E.g. if the buffer is 2048 and the hop size is 48 then you get 2000x0 and 48 filled audio samples
@param zeroPadFirstBuffer true if the buffer should be zeroPadFirstBuffer, false otherwise.

public void setZeroPadLastBuffer(boolean zeroPadLastBuffer) {
this.zeroPadLastBuffer = zeroPadLastBuffer;
} |
If zero pad last buffer is true then the last buffer is filled with zeros until the normal amount
of elements are present in the buffer. Otherwise the buffer only contains the last elements and no zeros.
By default it is set to true.
@param zeroPadLastBuffer A boolean to control whether the last buffer is zero-padded.

Reads the next audio block. It tries to read the number of bytes defined
by the audio buffer size minus the overlap. If the expected number of
bytes could not be read either the end of the stream is reached or
something went wrong.
The behavior for the first and last buffer is defined by their corresponding the zero pad settings. The method also handles the case if
the first buffer is also the last.
@return The number of bytes read.
@throws IOException
When something goes wrong while reading the stream. In
particular, an IOException is thrown if the input stream has
been closed.
