Actor

The Actor may be in different states of activity. These are not primary, internal states, but are derived from the Phase and Stop situation the actor is in. For the user, this is informational only, since the state may change any time. However, you may assume the activity state may only increase.

Use the Anonymous Actor as a sender if you do not have a context or do want to reveal yourself. It is not possible to return an answer to the Anonymous sender. Also, trying to stop it will fail.

Stopping of an actor is organised in levels of severity. The lowest level (Direct) terminates directly, the highest level never terminates. The latter is the default. Levels can always be decreased, increase is only possible if the action was not yet started (never for Direct and Finish).
