Method Detail

getPartitionName

public String getPartitionName()

Name of the underlying partition that determine the cluster to use.

setPartitionName

public void setPartitionName(String partitionName)

Set the name of the underlying partition that determine the cluster to use. Can be set only when the MBean is not in a STARTED or STARTING state.

callMethodOnPartition

public void callMethodOnPartition(String methodName,
                                  Object[] args)
                           throws Exception

Convenience method for broadcasting a call to all members of a partition.

Parameters:: methodName -; args -
Throws:: Exception

getDistributedState

public Serializable getDistributedState(String key)

Convenience method for sharing state across a cluster partition. Delegates to the DistributedStateService

Parameters:: key - key for the distributed object
Returns:: Serializable the distributed object

setDistributedState

public void setDistributedState(String key,
                                Serializable value)
                         throws Exception
