Examples of org.apache.ojb.broker.metadata.ObjectReferenceDescriptor

org.apache.ojb.broker.metadata.ObjectReferenceDescriptor
Describes a Field containing a reference to another class. Provides handling for foreign keys etc.
Note: Be careful when use references of this class or caching instances of this class, because instances could become invalid (see {@link MetadataManager}). @author Thomas Mahler
