Method Details

getSourceVariableDescriptor

public VariableDescriptor<Solution_> getSourceVariableDescriptor()

Specified by:

getSourceVariableDescriptor in interface SourcedVariableListener<Solution_,ListElementsChangeEvent<Object>>

resetWorkingSolution

public void resetWorkingSolution(InnerScoreDirector<Solution_,?> scoreDirector)

Description copied from interface: InnerVariableListener

Called when the entire working solution changes. In this event, the other before..()/after...() methods will not be called. At this point, implementations should clear state, if any.

Specified by:

resetWorkingSolution in interface InnerVariableListener<Solution_,ListElementsChangeEvent<Object>>

beforeChange

public void beforeChange(InnerScoreDirector<Solution_,?> scoreDirector,
 ListElementsChangeEvent<Object> event)

Specified by:

beforeChange in interface InnerVariableListener<Solution_,ListElementsChangeEvent<Object>>

afterChange

public void afterChange(InnerScoreDirector<Solution_,?> scoreDirector,
 ListElementsChangeEvent<Object> event)

Specified by:

afterChange in interface InnerVariableListener<Solution_,ListElementsChangeEvent<Object>>

getEntitiesMissingBeforeAfterEvents

public List<String> getEntitiesMissingBeforeAfterEvents(List<VariableId<Solution_>> changedVariables)

demand

public ListVariableTracker<Solution_>.TrackerDemand demand()

afterListElementUnassigned

public void afterListElementUnassigned(InnerScoreDirector<Solution_,?> scoreDirector,
 Object unassignedElement)

Specified by:
