java.lang.Object org.eclipse.persistence.indirection.IndirectSet
public class IndirectSet
IndirectSet is an example implementation of the Set protocol that allows a domain class to take advantage of TopLink Indirection without having to declare its instance variable as a ValueHolderInterface.
To use an IndirectSet:
