Constructor Detail

DefaultIoFuture

public DefaultIoFuture(IoSession session)

Creates a new instance associated with an IoSession.

Parameters:

session - an IoSession which is associated with this future

Method Detail

getSession

public IoSession getSession()

Specified by:

getSession in interface IoFuture

Returns:

the IoSession which is associated with this future.

join

@Deprecated
public void join()

Deprecated. Replaced with awaitUninterruptibly().

Specified by:

join in interface IoFuture

join

@Deprecated
public boolean join(long timeoutMillis)

Deprecated. Replaced with awaitUninterruptibly(long).

Specified by:

join in interface IoFuture

Parameters:

timeoutMillis - The time to wait for the join before bailing out

Returns:

true if the join was successful

await

public IoFuture await()
               throws InterruptedException

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

Specified by:

await in interface IoFuture

Returns:

The instance of IoFuture that we are waiting for

Throws:

InterruptedException - If the thread is interrupted while waiting

await

public boolean await(long timeout,
                     TimeUnit unit)
              throws InterruptedException

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

Specified by:

await in interface IoFuture

Parameters:

timeout - The maximum delay to wait before getting out

unit - the type of unit for the delay (seconds, minutes...)

Returns:

true if the operation is completed.

Throws:

InterruptedException - If the thread is interrupted while waiting

await

public boolean await(long timeoutMillis)
              throws InterruptedException

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

Specified by:

await in interface IoFuture

Parameters:

timeoutMillis - The maximum milliseconds to wait before getting out

Returns:

true if the operation is completed.

Throws:

InterruptedException - If the thread is interrupted while waiting

awaitUninterruptibly

public IoFuture 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 IoFuture

Returns:

the current IoFuture

awaitUninterruptibly

public boolean awaitUninterruptibly(long timeout,
                                    TimeUnit unit)

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

Specified by:

awaitUninterruptibly in interface IoFuture

Parameters:

timeout - The maximum delay to wait before getting out

unit - the type of unit for the delay (seconds, minutes...)

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 IoFuture

Parameters:

timeoutMillis - The maximum milliseconds to wait before getting out

Returns:

true if the operation is finished.

isDone

public boolean isDone()

Specified by:

isDone in interface IoFuture

Returns:

true if the operation is completed.

setValue

public boolean setValue(Object newValue)

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

Parameters:

newValue - The result to store into the Future

Returns:

true if the value has been set, false if the future already has a value (thus is in ready state)

getValue

protected Object getValue()

Returns:

the result of the asynchronous operation.

addListener

public IoFuture addListener(IoFutureListener<?> 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 IoFuture

Parameters:

listener - The listener to add

Returns:

the current IoFuture

removeListener

public IoFuture removeListener(IoFutureListener<?> listener)

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

Specified by:

removeListener in interface IoFuture

Parameters:

listener - The listener to remove

Returns:

the current IoFuture
