Constructor Detail

Tuple2Future

public Tuple2Future()

Create a future that is already done.

Parameters:

result - The result, if any.

Tuple2Future

public Tuple2Future(E result1,
                    F result2)

Create a future that is already done.

Parameters:

result - The result, if any.

Tuple2Future

public Tuple2Future(java.lang.Exception exception)

Create a future that is already done (failed).

Parameters:

exception - The exception.

Method Detail

getFirstResult

public E getFirstResult()

Get the first result.

Specified by:

getFirstResult in interface ITuple2Future<E,F>

Returns:

The next intermediate result.

Throws:

NoSuchElementException, - when there are no more intermediate results and the future is finished.

getSecondResult

public F getSecondResult()

Get the second result.

Specified by:

getSecondResult in interface ITuple2Future<E,F>

Returns:

The next intermediate result.

Throws:

NoSuchElementException, - when there are no more intermediate results and the future is finished.

setFirstResult

public void setFirstResult(E result)

Set the result. Listener notifications occur on calling thread of this method.

Parameters:

result - The result.

setSecondResult

public void setSecondResult(F result)

Set the result. Listener notifications occur on calling thread of this method.

Parameters:

result - The result.

setFirstResultIfUndone

public void setFirstResultIfUndone(E result)

Set the result. Listener notifications occur on calling thread of this method.

Parameters:

result - The result.

addTuple2ResultListener

public void addTuple2ResultListener(IFunctionalResultListener<E> firstListener,
                                    IFunctionalResultListener<F> secondListener)

Uses two functional result listeners to create a Tuple2ResultListener and add it. The first listener is called upon reception of the first result, the second is called for the second result. Exceptions will be logged to console.

Specified by:

addTuple2ResultListener in interface ITuple2Future<E,F>

Parameters:

firstListener - Listener for the first available result.

secondListener - Listener for the second available result.

addTuple2ResultListener

public void addTuple2ResultListener(IFunctionalResultListener<E> firstListener,
                                    IFunctionalResultListener<F> secondListener,
                                    IFunctionalExceptionListener exceptionListener)

Uses two functional result listeners to create a Tuple2ResultListener and add it. The first listener is called upon reception of the first result, the second is called for the second result. Additionally, a given exception listener is called when exceptions occur.

Specified by:

addTuple2ResultListener in interface ITuple2Future<E,F>

Parameters:

firstListener - Listener for the first available result.

secondListener - Listener for the second available result.

exListener - The listener that is called on exceptions. Passing null enables default exception logging.

setSecondResultIfUndone

public void setSecondResultIfUndone(F result)

Set the result. Listener notifications occur on calling thread of this method.

Parameters:

result - The result.

setXResult

protected void setXResult(int idx,
                          java.lang.Object res)

Set the xth result.

setXResultIfUndone

protected void setXResultIfUndone(int idx,
                                  java.lang.Object res)

Set the xth result.

getXResult

protected java.lang.Object getXResult(int idx)

Get the x result.

Returns:

The next intermediate result.

Throws:

NoSuchElementException, - when there are no more intermediate results and the future is finished.

findResult

protected TupleResult findResult(int idx)

Find result in results

getMax

protected int getMax()

Get the number of results of the type of future..

notifyIntermediateResult

protected void notifyIntermediateResult(IIntermediateResultListener<TupleResult> listener,
                                        TupleResult result)

Notify a result listener.

Overrides:

notifyIntermediateResult in class IntermediateFuture<TupleResult>

Parameters:

listener - The listener.
