java.lang.Object

ai.timefold.solver.core.impl.domain.variable.listener.support.violation.VariableTracker.TrackerDemand

All Implemented Interfaces:

Demand<VariableTracker<Solution_>>

Enclosing class:

VariableTracker<Solution_>

public class VariableTracker.TrackerDemand
extends Object
implements Demand<VariableTracker<Solution_>>

In order for the VariableTracker to be registered as a variable listener, it needs to be passed to the InnerScoreDirector.getSupplyManager(), which requires a Demand.

Unlike most other Demands, there will only be one instance of VariableTracker in the InnerScoreDirector for each variable.
