In UML models, a time event is
an event that represents the passage of a defined period of time or
an absolute time. A transition with a time event trigger initiates
when the time value is satisfied.
Before you begin
Before you can add a trigger to
a transition, you must have a state machine diagram open in the
Modeling perspective.
Procedure
- Right-click a transition; then click .
- Complete one of the following steps:
- To create a new time event, click Create Time Event,
type a name, and press Enter.
- To select an existing time event, click Select
Existing Element, and in the Select Element window,
click a time event, and click OK. Type a name
and press Enter.
Results
The time event is added to the transition in the diagram and
in the
Project Explorer view. You can view and
modify details about the time event in the
Properties view,
on the Triggers page for the selected transition.
