public interface HGHandle
HGHandle represents a reference to a hypergraph atom.
are completely managed by HyperGraphDB and should be treated by applications as abstract
A handle holds the system-level identity of an atom. HyperGraphDB will return concrete implementations of this interface depending on configuration, context of usage and similar considerations. In other words, a handle is essentially a reference token. One can think of a handle as a memory location, or simply a unique identifier.
Generally, handles are only valid during the run-time of a system. To obtain a permanent handle,
one which transcends system startup and shutdown, the
method should be used. Persistent handles are generated by a
when the database is open.
