pack-priv final Class FastLz

Level 1 is the fastest compression and generally useful for short data.

Level 2 is slightly slower but it gives better compression ratio.

In this case compress(ByteBuf, int, int, ByteBuf, int, int) will choose level automatically depending on the length of the input buffer. If length less than MIN_RECOMENDED_LENGTH_FOR_LEVEL_2 LEVEL_1 will be chosen, otherwise LEVEL_2.

Do not call compress(ByteBuf, int, int, ByteBuf, int, int) for input buffers which length less than this value.

The output buffer must be at least 6% larger than the input buffer and can not be smaller than 66 bytes.

Parameters

inputLength:int

length of input buffer

Returns:int

Maximum output buffer length

Compress a block of data in the input buffer and returns the size of compressed block. The size of input buffer is specified by length. The minimum input buffer size is 32. If the input is not compressible, the return value might be larger than length (input buffer size).

Annotations

@SuppressWarnings:IdentityBinaryExpression

Decompress a block of compressed data and returns the size of the decompressed block. If error occurs, e.g. the compressed data is corrupted or the output buffer is not large enough, then 0 (zero) will be returned instead. Decompression is memory safe and guaranteed not to write the output buffer more than what is specified in outLength.
