com.ibm.websphere.personalization
Class RuleTrigger

java.lang.Object
  com.ibm.websphere.personalization.RuleTrigger

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

ContentSpot

public class RuleTrigger
extends java.lang.Object
implements java.io.Serializable

This class is used to trigger a Personalization rule.

Typically this class makes Resources available through an indexed Content property. RuleTrigger will initialize the triggering method, using the RequestContext it obtains from the PersonalizationContext. The Personalization Context is always used as the target object when triggering Personalization Rules.

Since:

8.5 CF08 Triggering of a WCM managed rule by name, e.g triggering a Segment Group by using the setRuleName method, is not supported. You must use the setRuleId method to indicate the rule to trigger if the rule is a WCM managed rule and you must use the UUID of the WCM managed rule item e.g. Segment Group. In this case you must enter the Id string in this format $[lib]UUID.
Examples

To execute a Segment Group called "mySegGroup" with a UUID of "d61d9ccb-8982-48c8-99cb-bf2aeb3b416a"in a WCM Library called "RulesHolder" in a JSP in Portal, the following series of calls would be issued.

 
      RuleTrigger ruleTrigger = new RuleTrigger();
      ruleTrigger.setRequest(portletRequest);
      ruleTrigger.setRuleId("$[lib]d61d9ccb-8982-48c8-99cb-bf2aeb3b416a");
      Object[] winingSegments = ruleTrigger.trigger();
