public class JavaBeanBinding extends JavaAbstractBinding
Acts as a HGAtomType for Java beans. Uses underlying
RecordType instance to manage the layout in the store, but
operates on actual bean instances instead of Records.

public Object make(HGPersistentHandle handle, LazyRef<HGHandle[]> targetSet, IncidenceSetRef incidenceSet)
HGAtomTypeConstruct a new run-time instance of a hypergraph atom. A plain node must
be constructed whenever the targetSet parameter is null or of
length 0. Otherwise, a HGLink instance must be constructed.
It is not required that all atom types be able to construct both plain (node)
atoms and HGLinks. It is up to an HGAtomType implementation
to support either or both. When a HGLink counterpart is not available
for a particular run-time type, an implementation may choose to create an instance
of the default link value holder implementation HGValuedLink, provided
by HyperGraph.
make in interface HGAtomTypemake in class JavaAbstractBindinghandle - The HGPersistentHandle of the atom value.targetSet - When the atom is a link, this parameter holds the target set of
the link. When the atom is a node, the parameter is an array of 0 length.incidenceSet - A lazy reference to the set of links pointing to this atom. This is
null if we are constructing an internal/nested value of some complex type.null.
In case the handle points to an invalid instance (inexisting or with
a erronous layout), the method should throw a HGException.public HGPersistentHandle store(Object instance)
HGAtomTypeStore a run-time instance of a hypergraph atom into the hypergraph HGStore
as a new atom.
store in interface HGAtomTypestore in class JavaAbstractBindinginstance - The atom instance.public void release(HGPersistentHandle handle)
HGAtomTypeRelease a hypergraph value instance from the persistent store.
This method should be called when a HGPersistentHandle
returned from the store is no longer in use.
