algorithmPerformed

public void algorithmPerformed(AlgorithmBase algorithm)

Description copied from interface: AlgorithmInterface

Called after an algorithm this listener is registered to exits (maybe successfully, maybe not). If the algorithm is run in a separate thread, this call will be made within that thread. If not, this call will be made from that same, shared thread.

Specified by:

algorithmPerformed in interface AlgorithmInterface

Parameters:

algorithm - the algorithm which has just completed
