Class CallInterceptor

java.lang.Object
  org.jboss.cache.commands.AbstractVisitor
      org.jboss.cache.interceptors.base.CommandInterceptor
          org.jboss.cache.interceptors.CallInterceptor

All Implemented Interfaces:

Visitor

public class CallInterceptor
extends CommandInterceptor

Always at the end of the chain, directly in front of the cache. Simply calls into the cache using reflection. If the call resulted in a modification, add the Modification to the end of the modification list keyed by the current transaction.

Although always added to the end of an optimistically locked chain as well, calls should not make it down to this interceptor unless it is a call the OptimisticNodeInterceptor knows nothing about.
