Action Notation

Actions of most types are depicted as a round-cornered rectangle containing the Action type and Action name, as follows:

Other types have their own specific notation, as shown:

Action Kind	Notation	See also
AcceptEvent		AcceptEvent Actions
AcceptEventTimer		AcceptEvent Actions
CallBehavior
CallOperation
SendSignal		SendSignal Action & BroadcastSignal Action

AcceptEvent Actions

For an Accept Event Action element, the Properties dialog contains a Triggers tab on which you define one or more triggers to denote the type of events accepted by the Action.

Field

Usage

See also

Name

Specify the name of the trigger.

Type

Specify the type of trigger: Call, Change, Signal or Time:

•	Call - specifies that the event is a CallEvent, which sends a message to the associated object by invoking an operation

•	Change - specifies that the event is a ChangeEvent, which indicates that the transition is the result of a change in value of an attribute

•	Signal - specifies that the event is a SignalEvent, which corresponds to the receipt of an asynchronous signal instance

•	Time - corresponds to a TimeEvent; which specifies a moment in time

Code generation for State Machines currently supports Change and Time trigger events only, and expects a specification value.

Specification

Specify the event instigating the Transition.

For an AcceptEventTimer Action, you can type a JavaScript expression in this field evaluating to the number of ticks to wait for.

SendSignal Action & BroadcastSignal Action

For these Action elements, you can model the signal to be sent and the associated arguments to be conveyed, using the Signal tab of the element Properties dialog.

Field/Button	Action
Signal	Click on the ( ... ) button and select the required signal from the Select Signal dialog.
Attribute	Click on the drop-down arrow and select the attribute (as previously created in the Signal element) with which the arguments are to be associated.
Value	Type the appropriate value for the attribute.
Add	Click on this button and select the appropriate ActionPins from the Select Pin dialog, to identify the arguments for the Signal. To assign more than one ActionPin, press ( Ctrl ) whilst you select each one.
Save	Click on this button to save your changes.

Structural Feature Actions

Enterprise Architect supports the following types of Structural Feature Actions:

•	AddStructuralFeatureValue

For these actions you can set Ports, Parts or Attributes as the target structural feature.
