Abstract Class UML 2.4.1::WriteVariableAction

Description:

WriteVariableAction is an abstract class for variable actions that change variable values.

Direct Superclasses: VariableAction

Direct Subclasses: RemoveVariableValueAction, AddVariableValueAction

Class Precedence List: WriteVariableAction, VariableAction, Action, ExecutableNode, ActivityNode, RedefinableElement, NamedElement, Element

Properties:

value : InputPin (0 1); -- source WriteVariableAction
variable : Variable (1 1); -- source VariableAction
context : Classifier (0 1); -- source Action
input : InputPin (0 *); -- source Action
isLocallyReentrant : Boolean (1 1); -- source Action
localPostcondition : Constraint (0 *); -- source Action
localPrecondition : Constraint (0 *); -- source Action

Constraint that must be satisfied when execution is started.
{composite}
Subsets: Element.ownedElement

output : OutputPin (0 *); -- source Action
handler : ExceptionHandler (0 *); -- source ExecutableNode
activity : Activity (0 1); -- source ActivityNode
inGroup : ActivityGroup (0 *); -- source ActivityNode
inInterruptibleRegion : InterruptibleActivityRegion (0 *); -- source ActivityNode

Interruptible regions containing the node.
Subsets: ActivityNode.inGroup
Opposite: InterruptibleActivityRegion.node

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
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: same_type() : Boolean;
Description: The type input pin is the same as the type of the variable.
Expression: self.value -> notEmpty() implies self.value.type = self.variable.type

Signature: multiplicity() : Boolean;
Description: The multiplicity of the input pin is 1..1.
The OCL used here is not normative.
Editor's notes: No multiplicity
Expression: self.value.is(1,1)
Original: self.value.multiplicity.is(1,1)

Operations:

No additional operations.
