DoubleQuantCompressor

public DoubleQuantCompressor(QuantizeOption quantizeOption,
 ICompressor<IntBuffer> compressor)

Method Details

compress

public boolean compress(DoubleBuffer buffer,
 ByteBuffer compressed)

Description copied from interface: ICompressor

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

Specified by:

compress in interface ICompressor<DoubleBuffer>

Parameters:

buffer - the buffer to compress.

compressed - the compressed data

Returns:

true if the compression succeeded.

decompress

public void decompress(ByteBuffer compressed,
 DoubleBuffer buffer)

Description copied from interface: ICompressor

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

Specified by:

decompress in interface ICompressor<DoubleBuffer>

Parameters:

compressed - the compressed data

buffer - the buffer to fill with the uncompressed data.
