Signal dialog box

Signals

Signals are specifications of asynchronous stimuli communicated between instances. Events and Data flows are representations (occurrences) of signals. By extension, signals are a representation of any kind of information that can travel between packages, classes, instances or messages. This information can be an object or a request.

The "Signal" dialog box contains four tabs - "Properties", "Notes", "Tagged values" and "Stereotypes". For information on these standard dialog box tabs, please see "Standard dialog box tabs".
