Compressor
Each data compression algorithm must implement this interface.
| Methods |
|---|
| int |
compress(byte[] in, int inLen, byte[] out, int outPos)
Compress a number of bytes.
|
| int |
compress(byte[] in, int inLen, byte[] out, int outPos)
Compress a number of bytes.
Parameters:
in - the input data
inLen - the number of bytes to compress
out - the output area
outPos - the offset at the output array
Returns:
the end position
|
| void |
expand(byte[] in, int inPos, int inLen, byte[] out, int outPos, int outLen)
Expand a number of compressed bytes.
|
| void |
expand(byte[] in, int inPos, int inLen, byte[] out, int outPos, int outLen)
Expand a number of compressed bytes.
Parameters:
in - the compressed data
inPos - the offset at the input array
inLen - the number of bytes to read
out - the output area
outPos - the offset at the output array
outLen - the size of the uncompressed data

| void |
setOptions(String options)
Set the compression options.
|
| void |
setOptions(String options)
Set the compression options. This may include settings for
higher performance but less compression.
Parameters:
