INITIAL VALUE |
|
- bad_value == 100 |
|
- encode_table == a pointer to an array of 64 chars |
|
- where x is a 6 bit value the following is true: |
|
- encode_table[x] == the base64 encoding of x |
|
- decode_table == a pointer to an array of UCHAR_MAX chars |
|
- where x is any char value: |
|
- if (x is a valid character in the base64 coding scheme) then |
|
- decode_table[x] == the 6 bit value that x encodes |
|
- else |
|
- decode_table[x] == bad_value |
|
|
|
CONVENTION |
|
- The state of this object never changes so just refer to its |
|
initial value. |
