Class JsonLzfCodec

java.lang.Object

com.github.cafapi.common.codecs.jsonlzf.JsonLzfCodec

All Implemented Interfaces:

Codec, Decoder

public class JsonLzfCodec
extends Object
implements Codec

Implementation of Codec that supports serialisation and deserialisation to and form JSON format that itself is compressed with a high-speed LZF algorithm. In some crude tests, this was resulting in data that was approximately 60% of the original JSON size with negligible performance impact.
