Action Behavior By Type

You can vary the behavior initiated by an Action element by defining (or even redefining) its type. In simulation, you can apply and observe a number of different behaviors using the Actions in the types and groups described in this table.

Action Types

Object Actions	Object Actions operate on an object in a specific way, such as creating, destroying or reading the object. They include: CreateObject DestroyObject and Read Self	Create Objects in a Simulation Destroy Objects in a Simulation Action Types
Variable Actions	Variable Actions have an association variable in the form of the Tagged Value variable with the value of the name of an object in run-time. They provide the variable not only as an object but also as a property (such as an attribute or Port) of an object. They include: ReadVariable WriteVariable ClearVariable AddVariableValue RemoveVariable	Variable Actions
StructuralFeature Actions	StructuralFeature Actions operate on a structural feature, namely an attribute of an Activity or of the classifier of an object. They include: ReadStructuralFeature WriteStructuralFeature ClearStructuralFeature AddStructuralFeatureValue RemoveStructuralFeatureValue	StructuralFeature Actions
Invocation and Accept Event Actions	Invocation and Accept Event actions define the Triggers and Signals of an event. They include: SendSignal BroadcastSignal AcceptEvent SendObject CallBehavior CallOperation AcceptCall	SendSignal Action & BroadcastSignal Action AcceptEvent Actions CallBehavior Action SendObject Action
Miscellaneous Actions	The ValueSpecificationAction evaluates a value; it must have an input value and some evaluating code as its behavior or effect.
