All Implemented Interfaces:

JDOArray, JDOElement, JDORelationship

public class JDOArrayImplCaching
extends JDOArrayImplDynamic

An instance of this class represents the JDO relationship metadata of a array relationship field. This caching implementation caches any calulated value to avoid re-calculating it if it is requested again.
