com.tinkerpop.frames.modules.typedgraph.TypeRegistry
A TypeRegistry for a {@link FramedGraph}. With a {@link TypeRegistry} the {@link FramedGraph} is able to store type-information on edges,and use stored type-information to construct vertices/edges based on type-information stored in the graph (runtime). @see TypeField @see TypeValue @see FramedGraph
