Remarks

A TriggerItem is the minimum information necessary to describe some “event” on an object. A TriggerItem does not include any specification of “pre” or “post” semantics; these are specified separately in the TriggerContext.

The most common TriggerItem represents the "event" of setting a property on an object. The minimum necessary information to describe this “event” is the type of the class and the name of the property. There is no requirement that a TriggerItem be a property set operation. It might just as easily be some non-set operation being performed on an object (i.e. the calling of some method on the object). For this reason, any TriggerItem is represented most simply by a type and a name.

If the Type is not the same type as the Verifier.ApplicableType, you'll need to combine the TriggerItem with navigation information in a TriggerLink.

A TriggerItem is added to a verifier with Verifier.AddTrigger.
