Event Types
The constraint event types are a list of event domain and type names. These represent the event types on which the filter will match.
Expression
In addition to matching one of the constraint event types, a event must also cause the constraint expression to evaluate to TRUE in order for the filter to match that event.
Result to Set
Mapping Filters onlyIf an event matches a constraint in a mapping filter, the Result to Set value is used by the admin or proxy object instead of the property value (if any) already associated with the event.
