Class UML 2.5::LoopNode

Description:

A LoopNode is a StructuredActivityNode that represents an iterative loop with setup, test, and body sections.

Direct Superclasses: StructuredActivityNode

Direct Subclasses:

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

Properties:

bodyOutput : OutputPin (0 *); -- source LoopNode

The OutputPins on Actions within the bodyPart, the values of which are moved to the loopVariable OutputPins after the completion of each execution of the bodyPart, before the next iteration of the loop begins or before the loop exits.

isLeaf : Boolean (1 1); -- source RedefinableElement
redefinedElement : RedefinableElement (0 *); -- source RedefinableElement

The RedefinableElement that is being redefined by this element.
{readonly}
Derived union with sources: (redefinedNode)

ownedComment : Comment (0 *); -- source Element
ownedElement : Element (0 *); -- source Element
owner : Element (0 1); -- source Element

Constraints:

No additional constraints.

Operations:

Signature: sourceNodes() : ActivityNode;
Description: Return the loopVariable OutputPins in addition to other source nodes for the LoopNode as a StructuredActivityNode.
Expression: result = (self.StructuredActivityNode::sourceNodes()->union(loopVariable))

Signature: allActions() : Action;
Description: Return only this LoopNode. This prevents Actions within the LoopNode from having their OutputPins used as bodyOutputs or decider Pins in containing LoopNodes or ConditionalNodes.
Expression: result = (self->asSet())
