Class KryoSimpleWritable

java.lang.Object

org.apache.giraph.writable.kryo.KryoSimpleWritable

All Implemented Interfaces:

KryoIgnoreWritable, org.apache.hadoop.io.Writable

Direct Known Subclasses:

PageRankWithKryoSimpleWritable.EdgeValue, PageRankWithKryoSimpleWritable.MessageValue, PageRankWithKryoSimpleWritable.VertexValue

public abstract class KryoSimpleWritable
extends Object
implements KryoIgnoreWritable

Class which you can extend to get all serialization/deserialization done automagically. Usage of this class is similar to KryoWritable but unlike KryoWritable, this class does not support recursive/nested objects to provide better performance. If the underlying stream is a kryo output stream than the read/write happens with a kryo object that doesn't track references, providing significantly better performance.
