Class UML 2.3::Substitution
Description:
A substitution is a relationship between two classifiers signifies that the substituting classifier complies with the contract specified by the contract classifier. This implies that instances of the substituting classifier are runtime substitutable where instances of the contract classifier are expected.Direct Superclasses: RealizationDirect Subclasses: Class Precedence List: Substitution, Realization, Abstraction, Dependency, PackageableElement, ParameterableElement, NamedElement, DirectedRelationship, Relationship, ElementProperties:
contract : Classifier (1 1); -- source Substitution substitutingClassifier : Classifier (1 1); -- source Substitution mapping : OpaqueExpression (0 1); -- source Abstraction client : NamedElement (1 *); -- source Dependency
supplier : NamedElement (1 *); -- source Dependency The element(s) independent of the client element(s), in the same respect
and the same dependency relationship. In some directed dependency relationships
(such as Refinement Abstractions), a common convention in the domain of
class-based OO software is to put the more abstract element in this role.
Despite this convention, users of UML may stipulate a sense of dependency
suitable for their domain, which makes a more abstract element dependent
on that which is more specific.Subsets: DirectedRelationship.target
