Method Detail

resultAvailable

public final void resultAvailable(java.util.Collection<E> result)

Called when the result is available.

Specified by:

resultAvailable in interface IResultListener<E>

Parameters:

result - The result.

intermediateResultAvailable

public final void intermediateResultAvailable(E result)

Called when an intermediate result is available.

Specified by:

intermediateResultAvailable in interface IIntermediateResultListener<E>

Parameters:

result - The result.

finished

public void finished()

Declare that the future is finished.

Specified by:

finished in interface IIntermediateResultListener<E>

customResultAvailable

public void customResultAvailable(java.util.Collection<E> result)

Called when the result is available.

Parameters:

result - The result.

exceptionOccurred

public void exceptionOccurred(java.lang.Exception exception)

Called when an exception occurred.

Specified by:

exceptionOccurred in interface IResultListener<E>

Parameters:

exception - The exception.

customIntermediateResultAvailable

public void customIntermediateResultAvailable(E result)

Called when an intermediate result is available.

Parameters:

result - The result.

maxResultCountAvailable

public void maxResultCountAvailable(int max)

Declare that the future result count is available. This method is only called for intermediate futures, i.e. when this method is called it is guaranteed that the intermediateResultAvailable method will be called as often as the result count indicates.

Specified by:

maxResultCountAvailable in interface IIntermediateResultListener<E>

commandAvailable

public void commandAvailable(java.lang.Object command)

Called when a command is available.

Specified by:

commandAvailable in interface IFutureCommandResultListener<E>

resultAvailableIfUndone

public void resultAvailableIfUndone(java.util.Collection<E> result)

Called when the result is available.

Specified by:

resultAvailableIfUndone in interface IUndoneResultListener<E>

Parameters:

result - The result.

exceptionOccurredIfUndone

public void exceptionOccurredIfUndone(java.lang.Exception exception)

Called when an exception occurred.

Specified by:

exceptionOccurredIfUndone in interface IUndoneResultListener<E>

Parameters:

exception - The exception.

intermediateResultAvailableIfUndone

public void intermediateResultAvailableIfUndone(E result)

Called when an intermediate result is available.

Specified by:

intermediateResultAvailableIfUndone in interface IUndoneIntermediateResultListener<E>

Parameters:

result - The result.

finishedIfUndone

public void finishedIfUndone()

Declare that the future is finished. This method is only called for intermediate futures, i.e. when this method is called it is guaranteed that the intermediateResultAvailable method was called for all intermediate results before.

Specified by:

finishedIfUndone in interface IUndoneIntermediateResultListener<E>

handleException

protected void handleException(java.lang.Exception e)

Handle an exception.
