public class EmbeddedPCMapping
extends EmbeddedMapping
implements MappingCallbacks

Mapping for a PC object embedded within another PC object (1-1 relation). Provides mapping for a single Java type (the PC type) to multiple datastore columns. Allows for nested embedded fields. Implements MappingCallbacks since if we are embedding a MappingCallbacks field (e.g a BLOB on Oracle) then we need in turn to call the underlying MappingCallbacks methods.
