    • learnInstanceEvent

      public boolean learnInstanceEvent(InstanceHeader instance)
      If the rule is in learning mode, determine if the type of the instance should be added to the list of types being processed. For this to happen, the instance header must include a valid type, the type must be an active type for this server and not already included in the list. Any errors discovered in the types, of this rule's set up result in a false result. No diagnostics are created because this method is called very frequently and the errors will be trapped and logged elsewhere.
      Parameters:
      instance - details of the instance to test
      Returns:
      boolean flag true if the instance should be saved as a learned instance.
