Class UML 2.5::StructuredActivityNode

Description:

A StructuredActivityNode is an Action that is also an ActivityGroup and whose behavior is specified by the ActivityNodes and ActivityEdges it so contains. Unlike other kinds of ActivityGroup, a StructuredActivityNode owns the ActivityNodes and ActivityEdges it contains, and so a node or edge can only be directly contained in one StructuredActivityNode, though StructuredActivityNodes may be nested.

Direct Superclasses: Namespace, ActivityGroup, Action

Direct Subclasses: SequenceNode, LoopNode, ExpansionRegion, ConditionalNode

Class Precedence List: StructuredActivityNode, Namespace, ActivityGroup, Action, ExecutableNode, ActivityNode, RedefinableElement, NamedElement, Element

Constraints:

No additional constraints.

Operations:

Signature: targetNodes() : ActivityNode;
Description: Return those ActivityNodes contained immediately within the StructuredActivityNode that may act as targets of edges owned by the StructuredActivityNode.
Expression: result = (node->union(output.oclAsType(ActivityNode)->asSet())-> union(node->select(oclIsKindOf(Action)).oclAsType(Action).input)->asSet())

Signature: sourceNodes() : ActivityNode;
Description: Return those ActivityNodes contained immediately within the StructuredActivityNode that may act as sources of edges owned by the StructuredActivityNode.
Expression: result = (node->union(input.oclAsType(ActivityNode)->asSet())-> union(node->select(oclIsKindOf(Action)).oclAsType(Action).output)->asSet())

Signature: containingActivity() : Activity;
Description: The Activity that directly or indirectly contains this StructuredActivityNode (considered as an Action).
Expression: result = (self.Action::containingActivity())

Signature: allOwnedNodes() : ActivityNode;
Description: Returns all the ActivityNodes contained directly or indirectly within this StructuredActivityNode, in addition to the Pins of the StructuredActivityNode.
Expression: result = (self.Action::allOwnedNodes()->union(node)->union(node->select(oclIsKindOf(Action)).oclAsType(Action).allOwnedNodes())->asSet())

Signature: allActions() : Action;
Description: Returns this StructuredActivityNode and all Actions contained in it.
Expression: result = (node->select(oclIsKindOf(Action)).oclAsType(Action).allActions()->including(self)->asSet())
