Method Details

addPhaseLifecycleListener

void addPhaseLifecycleListener(PhaseLifecycleListener<Solution_> phaseLifecycleListener)

Add a PhaseLifecycleListener that is only notified of the phase and the step starting/ending events from this phase (and the solving events too of course).

To get notified for all phases, use AbstractSolver.addPhaseLifecycleListener(PhaseLifecycleListener) instead.

Parameters:

phaseLifecycleListener - never null

removePhaseLifecycleListener

void removePhaseLifecycleListener(PhaseLifecycleListener<Solution_> phaseLifecycleListener)

Parameters:

phaseLifecycleListener - never null
