从接口复制的说明: BlockDecompressor

Decompress source data read from src and write the decompressed data to dst.

指定者:

decompress 在接口中 BlockDecompressor

参数:

src - Compressed data to read from

srcOff - The start offset of compressed data

srcLen - The length of data which want to be decompressed

dst - The target to write decompressed data

dstOff - The start offset to write the decompressed data

返回:

Length of decompressed data

抛出:

BufferDecompressionException - if exception thrown when decompressing
