Package org.optaplanner.core.api.score.buildin.simpledouble

Class SimpleDoubleScoreHolder

java.lang.Object

org.optaplanner.core.api.score.holder.AbstractScoreHolder<SimpleDoubleScore>

org.optaplanner.core.api.score.buildin.simpledouble.SimpleDoubleScoreHolder

All Implemented Interfaces:

Serializable, ScoreHolder<SimpleDoubleScore>

@Deprecated
public class SimpleDoubleScoreHolder
extends AbstractScoreHolder<SimpleDoubleScore>

Deprecated.

Double-based scores are deprecated as floating point numbers are not associative (A + B + C == C + B + A) and therefore they are not compatible with incremental score calculation. Use SimpleBigDecimalScoreHolder or a scaled SimpleLongScoreHolder instead.

WARNING: NOT RECOMMENDED TO USE DUE TO ROUNDING ERRORS THAT CAUSE SCORE CORRUPTION. Use SimpleBigDecimalScoreHolder instead.

configureConstraintWeight

public void configureConstraintWeight(org.kie.api.definition.rule.Rule rule,
                                      SimpleDoubleScore constraintWeight)

Deprecated.

Description copied from interface: ScoreHolder

Sets up a ConstraintWeight from the ConstraintConfiguration during initialization.

Specified by:

configureConstraintWeight in interface ScoreHolder<SimpleDoubleScore>

Overrides:

configureConstraintWeight in class AbstractScoreHolder<SimpleDoubleScore>

Parameters:

rule - never null

constraintWeight - never null, with Score.getInitScore() equal to 0.

penalize

public void penalize(org.kie.api.runtime.rule.RuleContext kcontext)

Deprecated.

Penalize a match by the ConstraintWeight negated.

Parameters:

kcontext - never null, the magic variable in DRL

penalize

public void penalize(org.kie.api.runtime.rule.RuleContext kcontext,
                     double weightMultiplier)

Deprecated.

Penalize a match by the ConstraintWeight negated and multiplied with the weightMultiplier for all score levels.

Parameters:

kcontext - never null, the magic variable in DRL

weightMultiplier - at least 0

reward

public void reward(org.kie.api.runtime.rule.RuleContext kcontext)

Deprecated.

Reward a match by the ConstraintWeight.

Parameters:

kcontext - never null, the magic variable in DRL

reward

public void reward(org.kie.api.runtime.rule.RuleContext kcontext,
                   double weightMultiplier)

Deprecated.

Reward a match by the ConstraintWeight multiplied with the weightMultiplier for all score levels.

Parameters:

kcontext - never null, the magic variable in DRL

weightMultiplier - at least 0

impactScore

public void impactScore(org.kie.api.runtime.rule.RuleContext kcontext)

Deprecated.

Description copied from class: AbstractScoreHolder

For internal use only, use penalize() or reward() instead.

Overrides:

impactScore in class AbstractScoreHolder<SimpleDoubleScore>

Parameters:

kcontext - never null

addConstraintMatch

public void addConstraintMatch(org.kie.api.runtime.rule.RuleContext kcontext,
                               double weight)

Deprecated.

Parameters:

kcontext - never null, the magic variable in DRL

weight - higher is better, negative for a penalty, positive for a reward

extractScore

public SimpleDoubleScore extractScore(int initScore)

Deprecated.

Description copied from interface: ScoreHolder

Extracts the Score, calculated by the KieSession for DroolsScoreDirector.

Should not be called directly, use ScoreDirector.calculateScore() instead.

Parameters:

initScore - <= 0, managed by OptaPlanner, needed as a parameter in the Score's creation method, see Score.getInitScore()

Returns:

never null, the Score of the working PlanningSolution
