Examples of org.apache.openjpa.persistence.TupleFactory

org.apache.openjpa.persistence.TupleFactory
A factory for tuples such that all instances created by a factory instance share the same TupleElements to save memory consumption.
All Tuple instances created by this factory access the TupleElememts contained in this factory. @author Pinaki Poddar @since 2.0.0
