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

Class DroolsCondition<PatternVar,T extends DroolsRuleStructure<PatternVar>>

java.lang.Object

org.optaplanner.core.impl.score.stream.drools.common.DroolsCondition<PatternVar,T>

Type Parameters:

T - type of Drools rule that we operate on

Direct Known Subclasses:

DroolsBiCondition, DroolsQuadCondition, DroolsTriCondition, DroolsUniCondition

public abstract class DroolsCondition<PatternVar,T extends DroolsRuleStructure<PatternVar>>
extends Object

Encapsulates the low-level rule creation and manipulation operations via the Drools executable model DSL (see PatternDSL.
