Method Detail

create

public static <Solution_> VariableListenerSupport<Solution_> create(InnerScoreDirector<Solution_,?> scoreDirector)

linkVariableListeners

public void linkVariableListeners()

demand

public <Supply_ extends Supply> Supply_ demand(Demand<Supply_> demand)

Description copied from interface: SupplyManager

Returns the Supply for a Demand, preferably an existing one. If the Supply doesn't exist yet (as part of the domain model or externalized), it creates and attaches it.

Specified by:

demand in interface SupplyManager

Type Parameters:

Supply_ - Subclass of Supply

Parameters:

demand - never null

Returns:

never null
