Class UML 2.3::Usage
Description:
A usage is a relationship in which one element requires another element (or set of elements) for its full implementation or operation. A usage is a dependency in which the client requires the presence of the supplier.Direct Superclasses: DependencyDirect Subclasses: Class Precedence List: Usage, Dependency, PackageableElement, ParameterableElement, NamedElement, DirectedRelationship, Relationship, ElementProperties:
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
visibility : VisibilityKind (1 1); -- source PackageableElement Indicates that packageable elements must always have a visibility, i.e.,
visibility is not optional.Redefines: NamedElement.visibility
Default value: PUBLIC
owningTemplateParameter : TemplateParameter (0 1); -- source ParameterableElement templateParameter : TemplateParameter (0 1); -- source ParameterableElement clientDependency : Dependency (0 *); -- source NamedElement name : String (0 1); -- source NamedElement nameExpression : StringExpression (0 1); -- source NamedElement The string expression used to define the name of this named element.{composite}
Subsets: Element.ownedElement
namespace : Namespace (0 1); -- source NamedElement qualifiedName : String (0 1); -- source NamedElement source : Element (1 *); -- source DirectedRelationship target : Element (1 *); -- source DirectedRelationship relatedElement : Element (1 *); -- source Relationship ownedComment : Comment (0 *); -- source Element ownedElement : Element (0 *); -- source Element The Elements owned by this element.{composite, readonly}
Derived union with sources: (ownedComment, nameExpression)
Opposite: Element.owner
owner : Element (0 1); -- source Element The Element that owns this element.{readonly}
Derived union with sources: (namespace, owningTemplateParameter)
Opposite: Element.ownedElement
