In Unified Modeling Language (UML) sequence diagrams,
when you create a destroy message, a stop node is created automatically
on the lifeline. However, you can manually create a stop node on
a lifeline to terminate the lifeline at a specific position.
You must have a sequence diagram with lifelines
open in the diagram editor.
To terminate a lifeline with a stop node:
- In the Palette, click Stop Node.
- On a lifeline, click where you want to terminate the
interaction instance.
The lifeline ends at the position of the stop node, which
is designated by a destruction marker (X).
Note: You cannot create a stop node above
messages or interaction fragments on a lifeline.
