Element: Completion transition

A completion transition does not have a condition because it does not have a guard condition that triggers a switch operation. Therefore it switches when the source state has been processed completely. During the next task cycle, a potentially assigned action is performed.

All outgoing transitions of a start state and a fork/join are completion transitions. A composite state usually also includes a completion transition.

When the source element is a fork/join, the outgoing arrow is drawn without a circle.
