[rules-users] How to dynamic remove or add the rules

[rjr201]

You need to pass an Agenda Filter to the runRules() method that will filter
which rules are allowed to run.

For example.. 

public class MyAgendaFilter implements AgendaFilter {
 	/** List of rule names to be allowed to fired*/
 	ArrayList<String> rulesToFire;
 	
 	public MyAgendaFilter() {
 		rulesToFire = new ArrayList<String>();
 	}

	/**
 	 * Adds a rule to list of rules to be allowed to fire
 	 * @param name Name of rule to be fired
 	 */
 	public void addRuleToFire(String name) {
 		rulesToFire.add(name);
 	}
 	
 	@Override
 	public boolean accept(Activation activation) {
 		if (rulesToFire.contains(activation.getRule().getName())) { 
 			return true;
 		} else {
 			return false;	
 		}
 	}
}

This can then be used as follows:

AgendaFilter filter = new MyAgendaFilter();
filter.addRuleToFire("Rule Name");
StatefulKnowledgeSession knowledgeSession =
kbase.newStatefulKnowledgeSession();
knowledgeSession.fireAllRules(filter);
