All Superinterfaces:: org.jboss.ha.jmx.HAServiceMBean, org.jboss.ha.singleton.HASingletonMBean, javax.management.NotificationBroadcaster, org.jboss.system.Service, org.jboss.system.ServiceMBean

All Known Implementing Classes:: HASingletonInvoker

public interface HASingletonInvokerMBean
extends org.jboss.ha.singleton.HASingletonMBean

The ha singleton invoker service extends the ha singleton service and adds the capability to invoke the singleton service from the cluster.

Nested Class Summary

static interface HASingletonInvokerMBean.Callback
          Contract layer that defines the interactions between the service and the ha invoker.

static interface HASingletonInvokerMBean.Proxy
          The proxy interface bound in JNDI.

Method Summary

HASingletonInvokerMBean.Callback getCallback()
          Get the callback of the invoker.

java.lang.String getJNDIName()
          Return the JNDI name under which the proxy is bound.

java.util.Properties getJNDIProperties()
          Return the JNDI configuration to lookup the proxy.

int getMaxRetries()
          Return the max number of retries when an invocation is done.

javax.management.ObjectName getProxyFactory()
          Return the name of the proxy factory to use.

long getRetryWaitingTimeMS()
          Return the time that the thread will sleep before looking up a proxy during fail over.

java.lang.Object invoke(java.lang.String methodName, java.lang.Class[] types, java.lang.Object[] args)
          Invoke the service through the invoker.

HASingletonInvokerMBean.Proxy lookupProxy()
          Return the proxy, if it is cached then it will return the cached proxy otherwise it will perform a JNDI lookup.
