Creating events
"Start" and "End" events are required in the description of the service assured by the exchange contract.
An event represents a fact or an action occurring in the system, such as updating client information. It is managed by a broker. An application indicates that it can produce the event by declaring that it publishes it. If an application is interested in an event, it declares that it subscribes to the event.
To create the exchange contract "End" event:
1. In the insert toolbar, click the
Event
button.
2. Click in the frame of the described exchange contract.
The Creation of Event dialog box appears.
3. In the Name box, enter "End".
4. In the Event Nature frame, select End.
5. Click Finish.
The exchange contract "End" event appears in the diagram.
