 <div class="block"><p>
  <b>Purpose</b>: Define a class through which Cache access can be
  intercepted.
  <p>
  <b>Description</b>: EclipseLink makes extensive use of caching
  functionality. This class provides the mechanism for intercepting the cache
  access. Once intercepted applications can allow the process to continue by
  calling the method on the class attribute targetIdentityMap as described in
  the API javadocs or redirect the process entirely. * As with IdentityMaps an
  entire class inheritance hierarchy will share the same interceptor.
  <p>
  To implement a CacheInterceptor users should subclass this class implementing
  those methods they wish to intercept.
  <p>
  <b>Configuration</b>: Interceptors may be added to a session by using a
  Session or Descriptor customizer to set the class name of the interceptor on
  the target ClassDescriptor through the method
  setCacheInterceptorClass(Class).</div>
