Package org.apache.tinkerpop.gremlin.structure.io.graphson

Class AbstractGraphSONTypeSerializer

  • Direct Known Subclasses:
    GraphSONTypeSerializerV2, GraphSONTypeSerializerV3
    public abstract class AbstractGraphSONTypeSerializer
extends org.apache.tinkerpop.shaded.jackson.databind.jsontype.TypeSerializer
    Extension of the Jackson's default TypeSerializer. An instance of this object will be passed to the serializers on which they can safely call the utility methods to serialize types and making it compatible with the version 2.0+ of GraphSON.

        protected abstract Class getClassFromObject​(Object o)
        We force only **one** translation of a Java object to a domain specific object. i.e. users register typeIDs and serializers/deserializers for the predefined types we have in the spec. Graph, Vertex, Edge, VertexProperty, etc... And **not** their implementations (TinkerGraph, DetachedVertex, TinkerEdge, etc..)
