## 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());
         }
       }
