Method Details

invokeAsync

public CompletionStage<?> invokeAsync(GlobalComponentRegistry gcr)
                               throws Throwable

Description copied from interface: GlobalRpcCommand

Invoke the command asynchronously.

Throws:

Throwable

getCacheName

public String getCacheName()

getCurrentCH

public ConsistentHash getCurrentCH()

getPendingCH

public ConsistentHash getPendingCH()

getPhase

public CacheTopology.Phase getPhase()

getAvailabilityMode

public AvailabilityMode getAvailabilityMode()

getTopologyId

public int getTopologyId()

supportedSince

public NodeVersion supportedSince()

Description copied from interface: ReplicableCommand

Returns a NodeVersion representing the Infinispan version in which this command was added. This value is used to ensure that when the cluster contains different Infinispan versions, only commands compatible with the oldest version are transmitted.

Abstract classes should not implement this method as the version should be specific to an individual implementation. Similarly, implementations which extend another ReplicableCommand should always override this method.

Returns:

a NodeVersion corresponding to the Infinispan version this command was added.

toString

public String toString()

Overrides:
