Package org.optaplanner.core.impl.heuristic.selector.common.decorator

Interface SelectionSorterWeightFactory<Solution_,T>

Type Parameters:

Solution_ - the solution type, the class with the PlanningSolution annotation

T - the selection type

All Known Subinterfaces:

PlanningEntity.NullDifficultyWeightFactory, PlanningVariable.NullStrengthWeightFactory

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface SelectionSorterWeightFactory<Solution_,T>

Creates a weight to decide the order of a collections of selections (a selection is a PlanningEntity, a planningValue, a Move or a Selector). The selections are then sorted by their weight, normally ascending unless it's configured descending.

Implementations are expected to be stateless. The solver may choose to reuse instances.
