Package ai.timefold.solver.core.impl.score.director.easy

Class EasyScoreDirector<Solution_,Score_ extends Score<Score_>>

java.lang.Object

ai.timefold.solver.core.impl.score.director.AbstractScoreDirector<Solution_,Score_,EasyScoreDirectorFactory<Solution_,Score_>>

ai.timefold.solver.core.impl.score.director.easy.EasyScoreDirector<Solution_,Score_>

Type Parameters:

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

Score_ - the score type to go with the solution

All Implemented Interfaces:

ScoreDirector<Solution_>, InnerScoreDirector<Solution_,Score_>, AutoCloseable, Cloneable

public class EasyScoreDirector<Solution_,Score_ extends Score<Score_>>
extends AbstractScoreDirector<Solution_,Score_,EasyScoreDirectorFactory<Solution_,Score_>>

Easy java implementation of ScoreDirector, which recalculates the Score of the working solution every time. This is non-incremental calculation, which is slow. This score director implementation does not support ScoreExplanation.getConstraintMatchTotalMap() and ScoreExplanation.getIndictmentMap().

Method Detail

getEasyScoreCalculator

public EasyScoreCalculator<Solution_,Score_> getEasyScoreCalculator()

calculateScore

public Score_ calculateScore()

Description copied from interface: InnerScoreDirector

Calculates the Score and updates the working solution accordingly.

Returns:

never null, the Score of the working solution

isConstraintMatchEnabled

public boolean isConstraintMatchEnabled()

Always false, ConstraintMatchTotals are not supported by this ScoreDirector implementation.

Returns:

false

getConstraintMatchTotalMap

public Map<String,ConstraintMatchTotal<Score_>> getConstraintMatchTotalMap()

ConstraintMatchs are not supported by this ScoreDirector implementation.

Returns:

throws IllegalStateException

Throws:

IllegalStateException - always

See Also:

InnerScoreDirector.getIndictmentMap()

getIndictmentMap

public Map<Object,Indictment<Score_>> getIndictmentMap()

ConstraintMatchs are not supported by this ScoreDirector implementation.

Returns:

throws IllegalStateException

Throws:

IllegalStateException - always

See Also:

InnerScoreDirector.getConstraintMatchTotalMap()

requiresFlushing

public boolean requiresFlushing()

Description copied from interface: InnerScoreDirector

Some score directors (such as the Drools-based) keep a set of changes that they only apply when InnerScoreDirector.calculateScore() is called. Until that happens, this set accumulates and could possibly act as a memory leak.

Returns:

true if the score director can potentially cause a memory leak due to unflushed changes.
