Method Summary

Modifier and Type	Method and Description
void	instantiateApp(RuleApp app, PosInOccurrence pio, Goal goal, RuleAppCostCollector collector) Instantiate an incomplete RuleApp.
boolean	isApprovedApp(RuleApp app, PosInOccurrence pio, Goal goal) Re-Evaluate a RuleApp.

Method Detail

isStopAtFirstNonCloseableGoal

boolean isStopAtFirstNonCloseableGoal()

Checks if the Strategy should stop at the first non closeable Goal.

Returns:

true stop, false continue on other Goals.

isApprovedApp

boolean isApprovedApp(RuleApp app,
                      PosInOccurrence pio,
                      Goal goal)

Re-Evaluate a RuleApp. This method is called immediately before a rule is really applied

Returns:

true iff the rule should be applied, false otherwise

instantiateApp

void instantiateApp(RuleApp app,
                    PosInOccurrence pio,
                    Goal goal,
                    RuleAppCostCollector collector)

Instantiate an incomplete RuleApp. This method is called when the AutomatedRuleApplicationManager comes across a rule application in which some schema variables are not yet instantiated, or which is in some other way incomplete. The strategy then has the opportunity to return/provide a list of (more) complete rule applications by feeding them into the provided RuleAppCostCollector.
