DefaultFuture

public DefaultFuture(java.lang.Object lock)

Creates a new instance.

Method Detail

await

public T await()
                       throws java.lang.InterruptedException

Wait for the asynchronous operation to complete. The attached listeners will be notified when the operation is completed.

Specified by:

await in interface Future<T extends Future>

Throws:

java.lang.InterruptedException

await

public boolean await(long timeout,
            java.util.concurrent.TimeUnit unit)
              throws java.lang.InterruptedException

Wait for the asynchronous operation to complete with the specified timeout.

Specified by:

await in interface Future<T extends Future>

Returns:

true if the operation is completed.

Throws:

java.lang.InterruptedException

await

public boolean await(long timeoutMillis)
              throws java.lang.InterruptedException

Wait for the asynchronous operation to complete with the specified timeout.

Specified by:

await in interface Future<T extends Future>

Returns:

true if the operation is completed.

Throws:

java.lang.InterruptedException

awaitUninterruptibly

public T awaitUninterruptibly()

Wait for the asynchronous operation to complete uninterruptibly. The attached listeners will be notified when the operation is completed.

Specified by:

awaitUninterruptibly in interface Future<T extends Future>

Returns:

the current IoFuture

awaitUninterruptibly

public boolean awaitUninterruptibly(long timeout,
                           java.util.concurrent.TimeUnit unit)

Wait for the asynchronous operation to complete with the specified timeout uninterruptibly.

Specified by:

awaitUninterruptibly in interface Future<T extends Future>

Returns:

true if the operation is completed.

awaitUninterruptibly

public boolean awaitUninterruptibly(long timeoutMillis)

Wait for the asynchronous operation to complete with the specified timeout uninterruptibly.

Specified by:

awaitUninterruptibly in interface Future<T extends Future>

Returns:

true if the operation is finished.

isDone

public boolean isDone()

Returns if the asynchronous operation is completed.

Specified by:

isDone in interface Future<T extends Future>

setValue

public void setValue(java.lang.Object newValue)

Sets the result of the asynchronous operation, and mark it as finished.

getValue

protected java.lang.Object getValue()

Returns the result of the asynchronous operation.

addListener

public T addListener(FutureListener<T> listener)

Adds an event listener which is notified when this future is completed. If the listener is added after the completion, the listener is directly notified.

Specified by:

addListener in interface Future<T extends Future>

removeListener

public T removeListener(FutureListener<T> listener)

Removes an existing event listener so it won't be notified when the future is completed.

Specified by:

removeListener in interface Future<T extends Future>

isCanceled

public boolean isCanceled()

cancel

public void cancel()
