Method Detail

isReady

Boolean isReady()
         throws InterruptedException

This method checks if the registry is not handling any tasks and is currently consistent.

Returns:

Returns true if this registry is consistent and not busy.

InterruptedException

waitUntilReady

void waitUntilReady()
             throws InterruptedException,
                    CouldNotPerformException

Method blocks until the registry is not handling any tasks and is currently consistent. Note: If you have just modified the registry this method can maybe return immediately if the task is not yet received by the registry controller. So you should prefer the futures of the modification methods for synchronization tasks.

Throws:

InterruptedException - is thrown in case the thread was externally interrupted.

CouldNotPerformException - is thrown if the wait could not be performed.

waitUntilReadyFuture

Future<Void> waitUntilReadyFuture()

Method blocks until the registry is not handling any tasks and is currently consistent. Note: If you have just modified the registry this method can maybe return immediately if the task is not yet received by the registry controller. So you should prefer the futures of the modification methods for synchronization tasks.

Returns:

a future which is finished if the registry is ready.
