Decoding with Code() function
|
||||
-----------------------------
|
||||
|
||||
You can request some interfaces before decoding
|
||||
- ICompressSetDecoderProperties2
|
||||
- ICompressSetFinishMode
|
||||
|
||||
If you need to decode full stream:
|
||||
{
|
||||
1) try to set full_decoding mode with ICompressSetFinishMode::SetFinishMode(1);
|
||||
2) call the Code() function with specified (inSize) and (outSize), if these sizes are known.
|
||||
}
|
||||
|
||||
If you need to decode only part of stream:
|
||||
{
|
||||
1) try to set partial_decoding mode with ICompressSetFinishMode::SetFinishMode(0);
|
||||
2) Call the Code() function with specified (inSize = NULL) and specified (outSize).
|
||||
}
|
||||
|
||||
Encoding with Code() function
|
||||
-----------------------------
|
||||
|
||||
You can request some interfaces :
|
||||
- ICompressSetCoderProperties - use it before encoding to set properties
|
||||
- ICompressWriteCoderProperties - use it before or after encoding to request encoded properties.
|
||||
|
||||
ICompressCoder2 is used when (numInStreams != 1 || numOutStreams != 1)
|
||||
The rules are similar to ICompressCoder rules

ICompressFilter
|
||||
Filter(Byte *data, UInt32 size)
|
||||
(size)
|
||||
converts as most as possible bytes required for fast processing.
|
||||
Some filters have (smallest_fast_block).
|
||||
For example, (smallest_fast_block == 16) for AES CBC/CTR filters.
|
||||
If data stream is not finished, caller must call Filter() for larger block:
|
||||
where (size >= smallest_fast_block).
|
||||
if (size >= smallest_fast_block)
|
||||
{
|
||||
The filter can leave some bytes at the end of data without conversion:
|
||||
if there are data alignment reasons or speed reasons.
|
||||
The caller can read additional data from stream and call Filter() again.
|
||||
}
|
||||
If data stream was finished, caller can call Filter() for (size < smallest_fast_block)
|
||||
|
||||
(data) parameter:
|
||||
Some filters require alignment for any Filter() call:
|
||||
1) (stream_offset % alignment_size) == (data % alignment_size)
|
||||
2) (alignment_size == 2^N)
|
||||
where (stream_offset) - is the number of bytes that were already filtered before.
|
||||
The callers of Filter() are required to meet these requirements.
|
||||
(alignment_size) can be different:
|
||||
16 : for AES filters
|
||||
4 or 2 : for some branch convert filters
|
||||
1 : for another filters
|
||||
(alignment_size >= 16) is enough for all current filters of 7-Zip.
|
||||
But the caller can use larger (alignment_size).
|
||||
Recommended alignment for (data) of Filter() call is (alignment_size == 64).
|
||||
Also it's recommended to use aligned value for (size):
|
||||
(size % alignment_size == 0),
|
||||
if it's not last call of Filter() for current stream.
|
||||
|
||||
returns: (outSize):
|
||||
if (outSize == 0) : Filter have not converted anything.
|
||||
So the caller can stop processing, if data stream was finished.
|
||||
if (outSize <= size) : Filter have converted outSize bytes
|
||||
if (outSize > size) : Filter have not converted anything.
|
||||
and it needs at least outSize bytes to convert one block

||||
(it's for crypto block algorithms).
