Class UML 2.4.1::Abstraction

Description:

An abstraction is a relationship that relates two elements or sets of elements that represent the same concept at different levels of abstraction or from different viewpoints.

Direct Superclasses: Dependency

Direct Subclasses: Realization, Manifestation

Class Precedence List: Abstraction, Dependency, PackageableElement, ParameterableElement, NamedElement, DirectedRelationship, Relationship, Element

Properties:

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.
