org.eclipse.persistence.sessions.interceptors.CacheKeyInterceptor
public class CacheKeyInterceptor
The CacheKeyInterceptor allows a Cache Interceptor implementation to wrap the EclipseLink CacheKey. The CacheKey is an object that wraps the object and maintains cached based information about the object like primary key, write lock value and locking. The EclipseLink runtime will access the CacheKey and directly when releasing locks.
