Class UML 2.5::Substitution

Description:

A substitution is a relationship between two classifiers signifying 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.

Properties:

contract : Classifier (1 1); -- source Substitution
substitutingClassifier : Classifier (1 1); -- source Substitution
mapping : OpaqueExpression (0 1); -- source Abstraction

An OpaqueExpression that states the abstraction relationship between the supplier(s) and the client(s). In some cases, such as derivation, it is usually formal and unidirectional; in other cases, such as trace, it is usually informal and bidirectional. The mapping expression is optional and may be omitted if the precise relationship between the Elements is not specified.
