@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. UseSimpleBigDecimalScoreHolder
or a scaledSimpleLongScoreHolder
instead.WARNING: NOT RECOMMENDED TO USE DUE TO ROUNDING ERRORS THAT CAUSE SCORE CORRUPTION. UseSimpleBigDecimalScoreHolder
instead.- See Also:

configureConstraintWeight
public void configureConstraintWeight(org.kie.api.definition.rule.Rule rule, SimpleDoubleScore constraintWeight)
Deprecated.Description copied from interface:ScoreHolder
Sets up aConstraintWeight
from theConstraintConfiguration
during initialization.- Specified by:
configureConstraintWeight
in interfaceScoreHolder<SimpleDoubleScore>
- Overrides:
configureConstraintWeight
in classAbstractScoreHolder<SimpleDoubleScore>
- Parameters:
rule
- never nullconstraintWeight
- never null, withScore.getInitScore()
equal to 0.
-
penalize
public void penalize(org.kie.api.runtime.rule.RuleContext kcontext)
Deprecated.Penalize a match by theConstraintWeight
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 theConstraintWeight
negated and multiplied with the weightMultiplier for all score levels.- Parameters:
kcontext
- never null, the magic variable in DRLweightMultiplier

-
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 classAbstractScoreHolder<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 DRLweight
- higher is better, negative for a penalty, positive for a reward
-
extractScore
public SimpleDoubleScore extractScore(int initScore)
Deprecated.Description copied from interface:ScoreHolder
Extracts theScore
, calculated by theKieSession
forDroolsScoreDirector
.Should not be called directly, use
ScoreDirector.calculateScore()
instead.- Parameters:
initScore
-<= 0
, managed by OptaPlanner, needed as a parameter in theScore
's creation method, seeScore.getInitScore()
- Returns:
- never null, the
Score
of the workingPlanningSolution
