org.goplanit.assignment.ltm.sltm.PasFlowShiftDestinationBasedExecutor

public class PasFlowShiftDestinationBasedExecutor
extends PasFlowShiftExecutor

Functionality to conduct a PAS flow shift based on underlying destination based bush approach. A destination-based bush approach no longer requires labelling and should therefore outperform origin-based alternatives.
