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

Class HardSoftDoubleScoreHolder

java.lang.Object

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

org.optaplanner.core.api.score.buildin.hardsoftdouble.HardSoftDoubleScoreHolder

All Implemented Interfaces:

Serializable, ScoreHolder<HardSoftDoubleScore>

@Deprecated
public class HardSoftDoubleScoreHolder
extends AbstractScoreHolder<HardSoftDoubleScore>

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 HardSoftBigDecimalScoreHolder or a scaled HardSoftLongScoreHolder instead.

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

Deprecated.

Description copied from interface: ScoreHolder

Sets up a ConstraintWeight from the ConstraintConfiguration during initialization.

Specified by:

configureConstraintWeight in interface ScoreHolder<HardSoftDoubleScore>

Overrides:

configureConstraintWeight in class AbstractScoreHolder<HardSoftDoubleScore>

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)
