Package org.hypergraphdb.type

Interface Summary

Interface	Description
HGAtomType	A HGAtomType is an object capable of translating run-time atom instances to/from data in HGStore as well as providing minimal semantic information about the entities being constructed in the form of a predicate, called subsumes that determines whether one entity is a specialization of another.
HGCompositeType	A HGCompositeType represents a HyperGraph type with several dimensions.
HGPrimitiveType<JavaType>	A HGPrimitiveType is a HGAtomType that store its values directly as raw byte data.
HGProjection	A HGProjection represents a dimension of a composite type.
HGRefCountedType	A marker interface indicating that a given HGAtomType implementation is reference-counted.
HGTypeSchema<TypeDescriptor>
JavaTypeMapper	A JavaTypeMapper is used to create HyperGraphDB type out of Java classes and to provide appropriate run-time representations.
ObjectFactory<T>	An ObjectFactory is capable of constructing concrete run-time instances of a certain Class.
TypeUtils.WrappedRuntimeInstance
