This tool creates a stimulus associated with a send
action on the diagram, creating at the same time the associated
link between sender and receiving instances.
All details tabs and properties are identical to to that
of stimulus in general (see Section 19.3, “Stimulus”).
Its graphical representation on the diagram is that of a
stimulus associated with a send action, i.e. a solid line with
half an open arrow head.
Because the current release of ArgoUML does not fully
implement actions, there is no enforcement of the
relationship to a send action.
