java.lang.Object java.util.Dictionary<K,V> java.util.Hashtable org.eclipse.persistence.indirection.IndirectMap
public class IndirectMap
IndirectMap allows a domain class to take advantage of TopLink indirection without having to declare its instance variable as a ValueHolderInterface.
To use an IndirectMap:
