18.14. Dependency

Dependency is a relationship between two model elements showing that one depends on the other.

Within the UML metamodel, Dependency is a sub-class of Relationship.

Dependency is represented as a dashed line with an open arrow head from the depending model element to that which it is dependent upon.

18.14.1. Dependency Details Tabs

The details tabs that are active for dependencies are as follows.

ToDoItem

Standard tab.

Properties

See Section 18.14.2, “Dependency Property Toolbar” and Section 18.14.3, “Property Fields For Dependency” below.

Documentation

Standard tab. See Section 13.4, “Documentation Tab”.

Presentation

Standard tab

[Note]Note

The values in the "bounds" field of the dependency are not editable, since they are determined by the properties of the endpoints of the line.

Tagged Values

Standard tab. In the UML metamodel, Dependency has no tagged values of its own, but through superclasses has the following standard tagged values defined.

  • derived (from the superclass, ModelElement). Values true, meaning the dependency relationship is redundant—it can be formally derived from other elements, or false meaning it cannot.

    [Note]Note

    Derived dependencies still have their value in analysis to introduce useful names or concepts.

18.14.2. Dependency Property Toolbar

Go up

Navigate up through the package structure of the model. For a dependency this will be the package containing the dependency.

New Stereotype

This creates a new Stereotype (see Section 16.6, “Stereotype”) for the selected dependency, navigating immediately to the properties tab for that stereotype.

Delete

This deletes the selected dependency from the model.

[Warning]Warning

This is a deletion from the model not just the diagram. To delete a dependency from the diagram, but keep it within the model, use the main menu Remove From Diagram (or press the Delete key).

18.14.3. Property Fields For Dependency

Name

Text box. The name of the dependency.

[Tip]Tip

It is quite common to leave dependencies unnamed.

[Note]Note

ArgoUML does not enforce any naming convention for associations.

[Note]Note

There is no representation of the name of a dependency on the diagram.

Stereotype

Drop down selector. Dependency has no standard stereotypes of its own under UML 1.3. and so ArgoUML does not provide any. The stereotype is shown between « and » above or across the generalization.

Navigate Stereotype

icon. If a stereotype has been selected, this will navigate to the stereotype property panel (see Section 16.6, “Stereotype”).

Namespace

Text box. Records the namespace for the dependency. This is the package hierarchy.

Suppliers

Text area. Lists the end of the relationship that is supplying what is needed by the other end.

Button 1 double click on a supplier will navigate to that element.

Clients

Text area. Lists the “depending” ends of the relationship, i.e. the end that makes use of the other end.

Button 1 double click on a client will navigate to that element.
