类 Lz4BlockDecompressor

java.lang.Object

org.apache.paimon.compression.Lz4BlockDecompressor

所有已实现的接口:

BlockDecompressor

public class Lz4BlockDecompressor
extends Object
implements BlockDecompressor

Decode data written with Lz4BlockCompressor. It reads from and writes to byte arrays provided from the outside, thus reducing copy time.

This class is copied and modified from LZ4BlockInputStream.

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
