Interface MBeanServerProxy

public interface MBeanServerProxy

MBeanServerProxy allows any cluster node that runs the Management service to obtain and set attributes or invoke methods on registered MBeans.

Application logic can use MBeanServerProxy as follows:

   Cluster          cluster  = CacheFactory.ensureCluster();
   Registry         registry = cluster.getManagement();
   MBeanServerProxy proxy    = registry.getMBeanServerProxy();
   String           sName    = registry.ensureGlobalName(
      "type=PartitionAssignment,service=partitioned,responsibility=DistributionCoordinator");

   String sStatusHA = (String) proxy.getAttribute(sName, "HAStatus");
