![]() Specifies the visibility of the imported PackageableElement within the importing Package. In some cases (such as a Trace Abstraction) the assignment of direction (that is, the designation of the client element) is at the discretion of the modeler, and is a stipulation. The element(s) dependent on the supplier element(s). 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. 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. The element(s) independent of the client element(s), in the same respect and the same dependency relationship. ![]() The keyword > is shown near the dashed arrow if the visibility is public otherwise, the keyword > is shown to indicate private visibility. ![]() It is also possible to control whether the imported element can be further imported.Īn element import is shown using a dashed arrow with an open arrowhead from the importing namespace to the imported element. The name of the packageable element or its alias is to be added to the namespace of the importing namespace. Package diagram can show both structure and dependencies between sub-systems or modules.Īn element import is defined as a directed relationship between an importing namespace and a packageable element. Definition Package diagram shows the arrangement and organization of model elements in middle to large scale project.
