Actor
Someone or something that interacts with the system (actor usage).
Actor is one of the friendly builder classes — the
name without a Builder/Usage/Definition suffix. It is a
subclass of Builder and produces a *Usage node.
Actor has no definition form — Actor('X', kind='definition') raises ValueError, because SysML v2
has no actor definition construct. (The generator
refuses rather than emit something it can't cast back.)
