Class UML 2.3::ValuePin

Description:

A value pin is an input pin that provides a value by evaluating a value specification.

Direct Superclasses: InputPin

Direct Subclasses:

Class Precedence List: ValuePin, InputPin, Pin, ObjectNode, TypedElement, ActivityNode, RedefinableElement, NamedElement, MultiplicityElement, Element

Properties:

value : ValueSpecification (1 1); -- source ValuePin
isControl : Boolean (1 1); -- source Pin
inState : State (0 *); -- source ObjectNode
isControlType : Boolean (1 1); -- source ObjectNode
ordering : ObjectNodeOrderingKind (1 1); -- source ObjectNode
selection : Behavior (0 1); -- source ObjectNode
upperBound : ValueSpecification (1 1); -- source ObjectNode
type : Type (0 1); -- source TypedElement
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
incoming : ActivityEdge (0 *); -- source ActivityNode
outgoing : ActivityEdge (0 *); -- source ActivityNode
redefinedNode : ActivityNode (0 *); -- source ActivityNode
isLeaf : Boolean (1 1); -- source RedefinableElement

Indicates whether it is possible to further redefine a RedefinableElement. If the value is true, then it is not possible to further redefine the RedefinableElement. Note that this property is preserved through package merge operations; that is, the capability to redefine a RedefinableElement (i.e., isLeaf=false) must be preserved in the resulting RedefinableElement of a package merge operation where a RedefinableElement with isLeaf=false is merged with a matching RedefinableElement with isLeaf=true: the resulting RedefinableElement will have isLeaf=false. Default value is false.
Default value: FALSE

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
isOrdered : Boolean (1 1); -- source MultiplicityElement
isUnique : Boolean (1 1); -- source MultiplicityElement
lower : Integer (0 1); -- source MultiplicityElement
lowerValue : ValueSpecification (0 1); -- source MultiplicityElement
upper : UnlimitedNatural (0 1); -- source MultiplicityElement
upperValue : ValueSpecification (0 1); -- source MultiplicityElement
ownedComment : Comment (0 *); -- source Element
ownedElement : Element (0 *); -- source Element
owner : Element (0 1); -- source Element

Constraints:

Signature: no_incoming_edges() : Boolean;
Description: Value pins have no incoming edges.
Expression: true

Signature: compatible_type() : Boolean;
Description: The type of value specification must be compatible with the type of the value pin.
Expression: true

Operations:

No additional operations.
