DroolsUniRuleStructure

public DroolsUniRuleStructure(org.drools.model.Variable<A> aVariable,
                              DroolsPatternBuilder<?> aPattern,
                              List<org.drools.model.RuleItemBuilder<?>> supportingRuleItems,

                              LongSupplier varialeIdSupplier)

Method Detail

getA

public org.drools.model.Variable<A> getA()

getPrimaryPattern

public DroolsPatternBuilder<Object> getPrimaryPattern()

Description copied from class: DroolsRuleStructure

Returns the pattern that the subsequent streams may further expand. Consider the following left-hand side of a Drools rule:

     $a1: A()
     $a2: A(this != $a1)
 

The primary pattern would be the latter one ($a2), as that is the pattern you would use to further expand your output in both $a1 and $a2.

Specified by:

getPrimaryPattern in class DroolsRuleStructure

Returns:

the primary pattern as defined

getSupportingRuleItems

public List<org.drools.model.RuleItemBuilder<?>> getSupportingRuleItems()

Description copied from class: DroolsRuleStructure

Every other pattern necessary for the DroolsRuleStructure.getPrimaryPattern() to function properly within the Drools rule's left-hand side. In the example rule (see DroolsRuleStructure.getPrimaryPattern(), this method would return one and only supporting RuleItemBuilder, the one representing $a1.

Specified by:

getSupportingRuleItems in class DroolsRuleStructure

Returns:

all supporting rule items as defined, in the correct order
