Abstract Class UML 2.5::Action

Description:

An Action is the fundamental unit of executable functionality. The execution of an Action represents some transformation or processing in the modeled system. Actions provide the ExecutableNodes within Activities and may also be used within Interactions.

Direct Superclasses: ExecutableNode

Direct Subclasses: VariableAction, ValueSpecificationAction, UnmarshallAction, TestIdentityAction, StructuredActivityNode, StructuralFeatureAction, StartClassifierBehaviorAction, ReplyAction, ReduceAction, ReclassifyObjectAction, ReadSelfAction, ReadLinkObjectEndQualifierAction, ReadLinkObjectEndAction, ReadIsClassifiedObjectAction, ReadExtentAction, RaiseExceptionAction, OpaqueAction, LinkAction, InvocationAction, DestroyObjectAction, CreateObjectAction, ClearAssociationAction, AcceptEventAction

Class Precedence List: Action, ExecutableNode, ActivityNode, RedefinableElement, NamedElement, Element

Constraints:

No additional constraints.

Operations:

Signature: context.1() : Classifier;
Description: The derivation for the context property.
Expression: result = (let behavior: Behavior = self.containingBehavior() in if behavior=null then null else if behavior._'context' = null then behavior else behavior._'context' endif endif)

Signature: containingBehavior() : Behavior;
Description:
Expression: result = (if inStructuredNode<>null then inStructuredNode.containingBehavior() else if activity<>null then activity else interaction endif endif )

Signature: allOwnedNodes() : ActivityNode;
Description: Returns all the ActivityNodes directly or indirectly owned by this Action. This includes at least all the Pins of the Action.
Expression: result = (input.oclAsType(Pin)->asSet()->union(output->asSet()))

Signature: allActions() : Action;
Description: Return this Action and all Actions contained directly or indirectly in it. By default only the Action itself is returned, but the operation is overridden for StructuredActivityNodes.
Expression: result = (self->asSet())
