Description copied from interface: CompressionCodec

Decompress a buffer.

Specified by:

decompress in interface CompressionCodec

Parameters:

allocator - the allocator for allocating memory for decompressed buffer.

compressedBuffer - the buffer to be decompressed. Implementation of this method should take care of releasing this buffer.

Returns:

the decompressed buffer.

getCodecName

public String getCodecName()

Description copied from interface: CompressionCodec

Gets the name of the codec.
