Operation_ isInitiatedBy Trigger_ Rule

Trigger_ Rule initiates Operation_

Gives the operation started by a trigger rule.

A trigger rule is not affected by whether an operation is polymorphic.
For example, an operation Fill Order can be initiated by a trigger rule
whether there is one way to do it or many.  If methods are added or
removed, or even if operation changes from object-oriented to
non-object-oriented, the trigger rule is not affected.  This means the
event diagrams using an operation are likewise unaffected.
