Class LZFEncoder

java.lang.Object
  org.elasticsearch.common.compress.lzf.LZFEncoder

public class LZFEncoder
extends java.lang.Object

Encoder that handles splitting of input into chunks to encode, calls ChunkEncoder to compress individual chunks and combines resulting chunks into contiguous output byte array.

Field Summary

static java.lang.ThreadLocal<ThreadLocals.CleanableValue<ChunkEncoder>>

cachedEncoder

Method Summary

static byte[]	encode(byte[] data)
static byte[]	encode(byte[] data, int length) Method for compressing given input data using LZF encoding and block structure (compatible with lzf command line utility).
static void	encode(java.io.OutputStream os, byte[] data, int length)
static byte[]	encodeWithCache(byte[] data, int length)
