public final class GraphObjectInfoGeneratorRegistry

extends java.lang.Object

The GraphObjectInfoGeneratorRegistry is responsible for managing the registration of EdgeInfoGenerator and NodeInfoGenerator instances.

The GraphObjectInfoGeneratorRegistry allows to register one instance of a EdgeInfoGenerator and one instance of a NodeInfoGenerator.
One of the two instances get called by the GraphAPI in case an EdgeInfo or a NodeInfo has to be recreated from its string representation.

Since it is not possible to register more than one instance of an EdgeInfoGenerator or a NodeInfoGenerator both of them must be able to generate each kind of EdgeInfo or NodeInfo that is used.

The registered EdgeInfoGenerator and NodeInfoGenerator instances are used by the GraphAPI to create new instances of EdgeInfo and NodeInfo instances. The indirectly automatic creation of these objects is needed for instance in case a GraphObject instance is serialized and afterwards deserialized for some reason.
