Class AbstractGryoClassResolver

java.lang.Object

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

Direct Known Subclasses:

GryoClassResolverV1d0, GryoClassResolverV3d0

public abstract class AbstractGryoClassResolver
extends Object

This mapper implementation of the ClassResolver helps ensure that all Vertex and Edge concrete classes get properly serialized and deserialized by stripping them of their concrete class name so that they are treated generically. See the getRegistration(Class) method for the core of this logic.
