ByteRiceCompressor

public ByteRiceCompressor(RiceCompressOption option)

Method Details

compress

public boolean compress(ByteBuffer buffer,
 ByteBuffer writeBuffer)

Description copied from interface: ICompressor

compress the buffer into the byte buffer. Attention enough space must already be allocated.

Parameters:

buffer - the buffer to compress.

writeBuffer - the compressed data

Returns:

true if the compression succeeded.

decompress

public void decompress(ByteBuffer readBuffer,
 ByteBuffer buffer)

Description copied from interface: ICompressor

Decompress the byte buffer and restore the buffer from it, again enough space must already be allocated.

Parameters:

readBuffer - the compressed data

buffer - the buffer to fill with the uncompressed data.
