Class FailoverValveInterceptor

java.lang.Object
  org.jboss.jms.client.container.FailoverValveInterceptor

All Implemented Interfaces:

FailureDetector

public class FailoverValveInterceptor
extends java.lang.Object
implements FailureDetector

An interceptor that acts as a failover valve: it allows all invocations to go through as long as there is no failover in progress (valve is open), and holds all invocations while client-side failover is taking place (valve is closed). The interceptor is also a failover detector, in that it catches "failure-triggering" exceptions, and notifies the failover command center. The interceptor fields org.jboss.jms.client.Valve's method calls. It is a PER_INSTANCE interceptor. An instance of this interceptor must guard access to each connection, session, producer, consumer and queue browser delegate.
