Method Detail

intermediateResultAvailable

public void intermediateResultAvailable(S result)

Process intermediate results for ranking.

Specified by:

intermediateResultAvailable in interface IIntermediateResultListener<S>

Parameters:

result - The result.

resultAvailable

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

Called when result is available.

Specified by:

resultAvailable in interface IResultListener<S>

Parameters:

result - The result.

exceptionOccurred

public void exceptionOccurred(java.lang.Exception exception)

Called when exception occurs.

Specified by:

exceptionOccurred in interface IResultListener<S>

Parameters:

exception - The exception.

finished

public void finished()

Description copied from interface: IIntermediateResultListener

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:

finished in interface IIntermediateResultListener<S>

maxResultCountAvailable

public void maxResultCountAvailable(int max)

Description copied from interface: IIntermediateResultListener

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 except an exception occurs.

Specified by:

maxResultCountAvailable in interface IIntermediateResultListener<S>

isFinished

public boolean isFinished()

Get the finished.

Returns:

The finished.

rankResults

protected void rankResults()

Rank the results and announce them

notifyResults

protected void notifyResults(java.util.List<Tuple2<S,java.lang.Double>> results)

notifyException

protected void notifyException(java.lang.Exception exception)
