Class DeadlockDetectingInterceptor

java.lang.Object
  org.infinispan.commands.AbstractVisitor
      org.infinispan.interceptors.base.CommandInterceptor
          org.infinispan.interceptors.DeadlockDetectingInterceptor

All Implemented Interfaces:

Visitor

public class DeadlockDetectingInterceptor
extends CommandInterceptor

This interceptor populates the DeadlockDetectingGlobalTransaction with appropriate information needed in order to accomplish deadlock detection. It MUST process populate data before the replication takes place, so it will do all the tasks before calling CommandInterceptor.invokeNextInterceptor(org.infinispan.context.InvocationContext, org.infinispan.commands.VisitableCommand).

Note: for local caches, deadlock detection dos NOT work for aggregate operations (clear, putAll).
