Class UML 2.3::JoinNode

Description:

Join nodes have a Boolean value specification using the names of the incoming edges to specify the conditions under which the join will emit a token.

Direct Superclasses: ControlNode

Direct Subclasses:

Class Precedence List: JoinNode, ControlNode, ActivityNode, RedefinableElement, NamedElement, Element

Properties:

isCombineDuplicate : Boolean (1 1); -- source JoinNode
joinSpec : ValueSpecification (0 1); -- source JoinNode
activity : Activity (0 1); -- source ActivityNode
inGroup : ActivityGroup (0 *); -- source ActivityNode
inInterruptibleRegion : InterruptibleActivityRegion (0 *); -- source ActivityNode
inPartition : ActivityPartition (0 *); -- source ActivityNode
inStructuredNode : StructuredActivityNode (0 1); -- source ActivityNode

Structured activity node containing the node.
Subsets: ActivityNode.inGroup
Opposite: StructuredActivityNode.node

incoming : ActivityEdge (0 *); -- source ActivityNode
outgoing : ActivityEdge (0 *); -- source ActivityNode
redefinedNode : ActivityNode (0 *); -- source ActivityNode
isLeaf : Boolean (1 1); -- source RedefinableElement
redefinedElement : RedefinableElement (0 *); -- source RedefinableElement
redefinitionContext : Classifier (0 *); -- source RedefinableElement
clientDependency : Dependency (0 *); -- source NamedElement

Indicates the dependencies that reference the client.
Opposite: Dependency.client

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: one_outgoing_edge() : Boolean;
Description: A join node has one outgoing edge.
Expression: self.outgoing->size() = 1

Signature: incoming_object_flow() : Boolean;
Description: If a join node has an incoming object flow, it must have an outgoing object flow, otherwise, it must have an outgoing control flow.
The OCL used here is not normative.
Editor's notes: oclIsTypeOf not isTypeOf, isEmpty not empty, missing ) but I am uncertain what this is trying to do.
Expression: true
Original: (self.incoming.select(e | e.isTypeOf(ObjectFlow)->notEmpty() implies self.outgoing.isTypeOf(ObjectFlow)) and (self.incoming.select(e | e.isTypeOf(ObjectFlow)->empty() implies self.outgoing.isTypeOf(ControlFlow))

Operations:

No additional operations.
