Method Detail

defineHGType

public HGAtomType defineHGType(java.lang.Class<?> javaClass,
                               HGHandle typeHandle)

Description copied from interface: JavaTypeMapper

Create a new HyperGraphDB type for the given Java class. The HGHandle of the type pre-created and provided as a parameter.

This method should return a brand new HGAtomType that will subsequently be saved as a type atom with handle typeHandle and associated with the javaClass class.

Specified by:

defineHGType in interface JavaTypeMapper

Returns:

getJavaBinding

public HGAtomType getJavaBinding(HGHandle typeHandle,
                                 HGAtomType hgType,
                                 java.lang.Class<?> javaClass)

Description copied from interface: JavaTypeMapper

Create a type wrapper for a given raw HyperGraphDB type. The type wrapper should work with the regular Java runtime instance of an atom and use the underlying HG type for actual storage and retrieval.

Specified by:

getJavaBinding in interface JavaTypeMapper

Returns:

setHyperGraph

public void setHyperGraph(HyperGraph graph)

Description copied from interface: HGGraphHolder

During load time, set the HyperGraph instance to which this atom belongs.
