Class KryoWriter

java.lang.Object

com.tinkerpop.gremlin.structure.io.kryo.KryoWriter

All Implemented Interfaces:

GraphWriter

public class KryoWriter
extends java.lang.Object
implements GraphWriter

The GraphWriter for the Gremlin Structure serialization format based on Kryo. The format is meant to be non-lossy in terms of Gremlin Structure to Gremlin Structure migrations (assuming both structure implementations support the same graph features).
