Package org.optaplanner.core.impl.score.stream.drools.common

Class DroolsCondition.ImmediatelyPreviousFilter<PredicateType>

java.lang.Object

org.optaplanner.core.impl.score.stream.drools.common.DroolsCondition.ImmediatelyPreviousFilter<PredicateType>

Type Parameters:

PredicateType - type of the predicate (uni, bi, ...) matching the stream

Enclosing class:

DroolsCondition<PatternVar,T extends DroolsRuleStructure<PatternVar>>

public final class DroolsCondition.ImmediatelyPreviousFilter<PredicateType>
extends Object

When two filters follow one another immediately, we merge them into a new Predicate. This is done for performance reasons, as filters are not indexed and therefore we only want to pay the penalty once. This class is a data carrier facilitating that feature.
