Visualization of Endpoints and Links


By default, endpoints are marked in a special way in the editors and in the Organizer. The markers are slightly different depending on whether or not any links are connected to the endpoint.

Endpoints in Graphical Editors

In the SDL Editor and the SDL Suite diagram editors, the endpoint marker is a small triangle in the upper left corner of the object's enclosing rectangle. The triangle is filled if the endpoint has any links connected to it.

For lines in the SDL, OM. SC and HMSC diagrams, the marker appears on the name or signal list associated with the line. In SDL diagrams, it is also possible to create endpoints on other text elements associated with the line.

For lines in MSC diagrams (messages, timers, create requests), the marker normally appears at the "start" end of the line.

You can hide the endpoint markers by changing the option Show Link Endpoints in the Editor Options in the View menu, or by setting the editor preference ShowLinks to off.

Note:

Endpoint markers are never shown when printing a diagram.

Endpoints in Text Editors

In the Text Editor, endpoints are shown as underlined text, regardless if they have links connected to them or not. The endpoint text can be shown as normal text by changing the option Show Link Endpoints in the Editor Options in the View menu, or by setting the Text Editor preference ShowLinks to off.

In the Emacs editor (on UNIX), endpoints without links are by default shown as blue, underlined text, whereas endpoints with links are shown as bold, blue, underlined text. The default font faces can be changed; see Type Faces for Endpoints.

In MS Word (in Windows), endpoints without links are shown as blue, underlined text, whereas endpoints with links are shown as bold, blue, double underlined text.

Endpoint text is always shown as normal text when printing a text document.

Endpoints in the Organizer

In the Organizer, the endpoint marker appears in the same way as in the graphical editors, i.e. a triangle in the upper left corner of the document icon.

The endpoint markers are always shown in the Organizer, and they are also shown when printing the Organizer window.
