Description:

A control flow is an edge that starts an activity node after the previous one is finished.

Direct Superclasses: ActivityEdge

Direct Subclasses:

Class Precedence List: ControlFlow, ActivityEdge, RedefinableElement, NamedElement, Element

Properties:

activity : Activity (0 1); -- source ActivityEdge
guard : ValueSpecification (1 1); -- source ActivityEdge
inGroup : ActivityGroup (0 *); -- source ActivityEdge
inPartition : ActivityPartition (0 *); -- source ActivityEdge

Partitions containing the edge.
Subsets: ActivityEdge.inGroup
Opposite: ActivityPartition.edge

inStructuredNode : StructuredActivityNode (0 1); -- source ActivityEdge
interrupts : InterruptibleActivityRegion (0 1); -- source ActivityEdge
redefinedEdge : ActivityEdge (0 *); -- source ActivityEdge
source : ActivityNode (1 1); -- source ActivityEdge

Node from which tokens are taken when they traverse the edge.
Opposite: ActivityNode.outgoing

target : ActivityNode (1 1); -- source ActivityEdge
weight : ValueSpecification (1 1); -- source ActivityEdge
isLeaf : Boolean (1 1); -- source RedefinableElement
redefinedElement : RedefinableElement (0 *); -- source RedefinableElement
redefinitionContext : Classifier (0 *); -- source RedefinableElement
clientDependency : Dependency (0 *); -- source NamedElement
name : String (0 1); -- source NamedElement
nameExpression : StringExpression (0 1); -- source NamedElement
namespace : Namespace (0 1); -- source NamedElement
qualifiedName : String (0 1); -- source NamedElement
visibility : VisibilityKind (0 1); -- source NamedElement
ownedComment : Comment (0 *); -- source Element
ownedElement : Element (0 *); -- source Element
owner : Element (0 1); -- source Element

Constraints:

Signature: object_nodes() : Boolean;
Description: Control flows may not have object nodes at either end, except for object nodes with control type.
Expression: true
