Sample text

By invoking rules in priority order, the framework provides business developers with the ability to ensure that some rules are invoked before others. Changes to ValidationRules The priority of a rule is set when the rule is associated with a property through the AddInstanceRule() or AddRule() methods. To support this concept, these methods have overloads that accept the priority value. AddRule(handler, new RuleArgs(propertyName), priority); } There are numerous overloads of each method, and I’m not going to list them all here.

This meets the goal of running less expensive rules first and only running more expensive rules if the inexpensive ones are satisfied. StringRequired rule Explicit Short-Circuiting Another approach to short-circuiting is to have a rule method explicitly indicate that no subsequent rules should be invoked for this property. Typically, you’ll use rule priorities to control the order in which rule methods are invoked, so you can predict which rules won’t be executed when short-circuiting occurs. Within a rule method, you can choose to stop the processing of all subsequent rule methods for the current property.

As an optimization, the code keeps track of whether the list has been sorted by using a Boolean field. Any time items are added to the list, this field is set to false , and after the sort is complete it is set to true. The pre-sorted result is returned on all subsequent calls. At this point, you should understand that a business developer can choose to specify a priority for each rule when calling AddRule() or AddInstanceRule(). This priority value is maintained by the RuleMethod objects, and is used by RulesList to perform the sort.
