Method Detail

setFuture

public void setFuture(java.util.concurrent.Future<T> future)

Description copied from interface: NotifyingNotifiableFuture

Setup the future which is wrapped by implementation of this interface. Warning: the implementation must synchronize the call setFuture() and notifyDone() to be executed in this order. Also, all calls delegated to the future must be deferred until the network future is set up.

Specified by:

setFuture in interface NotifyingNotifiableFuture<T>

getFuture

public java.util.concurrent.Future<T> getFuture()
                                         throws java.lang.InterruptedException

Throws:

java.lang.InterruptedException

cancel

public boolean cancel(boolean mayInterruptIfRunning)

Specified by:

cancel in interface java.util.concurrent.Future<T>

isCancelled

public boolean isCancelled()

isCancelled in interface java.util.concurrent.Future<T>

isDone

public boolean isDone()

Specified by:

isDone in interface java.util.concurrent.Future<T>

get

public T get()
      throws java.lang.InterruptedException,
             java.util.concurrent.ExecutionException

Specified by:

get in interface java.util.concurrent.Future<T>

Throws:

get

public T get(long timeout,
    java.util.concurrent.TimeUnit unit)
      throws java.lang.InterruptedException,
             java.util.concurrent.ExecutionException,
             java.util.concurrent.TimeoutException

Specified by:

get in interface java.util.concurrent.Future<T>

Throws:

java.lang.InterruptedException

java.util.concurrent.ExecutionException

java.util.concurrent.TimeoutException

notifyDone

public void notifyDone(T result)

Description copied from interface: NotifyingNotifiableFuture

Notify the listeners that the operation has finished. Subsequent calls for isDone() will return true and subsequent calls for get() will return the provided result.

Specified by:

notifyDone in interface NotifyingNotifiableFuture<T>

notifyException

public void notifyException(java.lang.Throwable exception)

Description copied from interface: NotifyingNotifiableFuture

Notify the listeners that the operation has finished. Subsequent calls for isDone() will return true and subsequent calls for get() will throw the provided exception.

Specified by:

notifyException in interface NotifyingNotifiableFuture<T>
