UML Designer User's Guide
Since we have created an Actor element to represent the librarian, we can
now indicate the relationship between this actor and the use case in which it
participates. One way to do this is with a hypertext link in the use
case description.
To insert a hypertext link for the Librarian actor, follow these
steps:
- Select Use Cases in the middle pane of the Relationships
Browser.
- Select Adding a new book to the catalog from the list of use
cases.
- In the text pane, select the word librarian in the use case
description. (You can do this with the keyboard, by swiping the mouse,
or by double-clicking on the word.)
- Select Insert Link>Reference from the pop-up menu of the
text pane. A window appears showing the different kinds of objects you
can link to.
- In this case, the object we want to link to is an actor, so select
Actor from the list. A list of available actors
appears; at this point, we have only created one actor,
Librarian, so no other choices appear.
- Select Librarian and then select OK.
- A window now appears verifying the label for this actor you want to appear
in the text of the use case (the label of a link can be different from the
name of the destination element). If you wanted to change the wording
of the reference to the librarian in the use case description, you could
change it here; for now, select OK to accept the
default.
An actor icon
appears beside the word librarian to indicate the existence of a
link to an actor in the model. You can follow this hypertext link by
double-clicking on the linked word. This opens a browser on the
Librarian actor.
