All Implemented Interfaces:

public class OptimisticReplicationInterceptor
extends BaseRpcInterceptor

Replication interceptor for the optimistically locked interceptor chain. Responsible for replicating state to remote nodes. Unlike it's cousin, the ReplicationInterceptor, this interceptor only deals with transactional calls. Just like all things to do with Optimistic Locking, it is a requirement that everything is done in a transaction and the transaction context is available via InvocationContext.getTransaction() and InvocationContext.getGlobalTransaction().
