java.lang.Objectorg.eclipse.persistence.descriptors.InterfacePolicy
public class InterfacePolicy
Purpose: Allows for a descriptor's implemented interfaces to be configured. Generally Interface Descriptors are used for 1 of 2 reasons:
a. Interface descriptors can be used to query across a set of classes that do not share a table.
b. As a target of a variable one to one mapping.
