Class TypeRegister

java.lang.Object

org.neo4j.ogm.context.register.TypeRegister

public class TypeRegister
extends Object

The TypeRegister maintains the list of active objects ids in the session, mapping each object id to its type hierarchy. Thus a domain object with id 5 of type Person extends Entity will have 2 entries in the type register, one in the Person map, and one in the Entity map.
