Class UML 2.3::RemoveVariableValueAction

Description:

A remove variable value action is a write variable action that removes values from variables.

Direct Superclasses: WriteVariableAction

Direct Subclasses:

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

Properties:

isRemoveDuplicates : Boolean (1 1); -- source RemoveVariableValueAction
removeAt : InputPin (0 1); -- source RemoveVariableValueAction
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

If true, the action can begin a new, concurrent execution, even if there is already another execution of the action ongoing. If false, the action cannot begin a new execution until any previous execution has completed.
Default value: FALSE

Constraints:

Signature: unlimited_natural() : Boolean;
Description: Actions removing a value from ordered non-unique variables must have a single removeAt input pin and no value input pin if isRemoveDuplicates is false. The removeAt pin must be of type Unlimited Natural with multiplicity 1..1. Otherwise, the action has a value input pin and no removeAt input pin.
Expression: if not self.variable.isOrdered or self.variable.isUnique or isRemoveDuplicates then self.removeAt -> isEmpty() and self.value -> notEmpty() else self.value -> isEmpty() and self.removeAt -> notEmpty() and self.removeAt.type = UnlimitedNatural and self.removeAt.lower() = 1 and self.removeAt.upper() = 1 endif
