A Self-Message reflects a new process or method invoked within the calling lifeline's operation. It is a specification of a Message, typically in a Sequence diagram.

Self-Message as Return

It is possible to depict a return from a Self Message call.


To create a Self Message return:

  1. Create a second Self Message at the end of execution.
  2. Double-click on the Message name to open the Message Properties dialog.
  3. Select the Is Return checkbox.
  4. Raise the Activation level of the return.

Self-Message Calls indicate a nested invocation; new activation levels are added with each Call.
