Class UML 2.4.1::SendSignalAction
Description:
A send signal action is an action that creates a signal instance from its
inputs, and transmits it to the target object, where it may cause the firing
of a state machine transition or the execution of an activity. The argument
values are available to the execution of associated behaviors. The requestor
continues execution immediately. Any reply message is ignored and is not
transmitted to the requestor. If the input is already a signal instance,
use a send object action.
