apply

public DmnDecisionTableEvaluationEvent apply(DmnDecisionTableEvaluationEvent decisionTableEvaluationEvent)

Description copied from interface: DmnHitPolicyHandler

Applies hit policy. Depending on the hit policy this can mean filtering and sorting of matching rules or aggregating results.

Specified by:

apply in interface DmnHitPolicyHandler

Parameters:

decisionTableEvaluationEvent - the evaluation event of the decision table

Returns:

the final evaluation result
