Class UML 2.3::RemoveStructuralFeatureValueAction

Description:

A remove structural feature value action is a write structural feature action that removes values from structural features.

Direct Superclasses: WriteStructuralFeatureAction

Direct Subclasses:

Class Precedence List: RemoveStructuralFeatureValueAction, WriteStructuralFeatureAction, StructuralFeatureAction, Action, ExecutableNode, ActivityNode, RedefinableElement, NamedElement, Element

Properties:

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

Specifies the position of an existing value to remove in ordered nonunique structural features. The type of the pin is UnlimitedNatural, but the value cannot be zero or unlimited.

Constraints:

Signature: non_unique_removal() : Boolean;
Description: Actions removing a value from ordered non-unique structural features 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.structuralFeature.isOrdered or self.structuralFeature.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
