Class GryoMapper

java.lang.Object

org.apache.tinkerpop.gremlin.structure.io.gryo.GryoMapper

All Implemented Interfaces:

Mapper<Kryo>

public final class GryoMapper
extends Object
implements Mapper<Kryo>

A Mapper implementation for Kryo. This implementation requires that all classes to be serialized by Kryo are registered to it.

Graph implementations providing an IoRegistry should register their custom classes and/or serializers in one of three ways:

1. Register just the custom class with a null Serializer implementation
2. Register the custom class with a Serializer implementation
3. Register the custom class with a Function<Kryo, Serializer> for those cases where the Serializer requires the Kryo instance to get constructed.

For example:

 
 public class MyGraphIoRegistry extends AbstractIoRegistry {
   public MyGraphIoRegistry() {
     register(GryoIo.class, MyGraphIdClass.class, new MyGraphIdSerializer());
   }
 }
