Class ESLZ4Decompressor

java.lang.Object
net.jpountz.lz4.LZ4FastDecompressor
org.elasticsearch.lz4.ESLZ4Decompressor
All Implemented Interfaces:
net.jpountz.lz4.LZ4Decompressor
public class ESLZ4Decompressor extends net.jpountz.lz4.LZ4FastDecompressor
This file is a vendored version of net.jpountz.lz4.LZ4JavaSafeFastDecompressor from yawkat/lz4-java. To obtain the original file, check out the lz4-java repository and run mvn clean install which will generate the original source of this class at target/generated-sources/mvel/net/jpountz/lz4/LZ4JavaSafeFastDecompressor.java.

It modifies the original implementation to use local LZ4SafeUtils and SafeUtils implementations which include some performance optimisations, and it also drops support for decompressing data from a direct (non-heap) ByteBuffer.

Differences from the original are annotated with [ES change from upstream]
