Properties of Elements in Component Diagrams

In a UML component diagram in Visual Studio Ultimate, each element on the diagram has properties. To see the properties of an element, right-click the element on the diagram or in UML Model Explorer and then click Properties. The properties appear in the Properties window. 

Note

This topic is about the properties of elements in UML Component Diagrams. For more information about how to read UML Component Diagrams, see UML Component Diagrams: Reference. For more information about how to draw UML Component Diagrams, see UML Component Diagrams: Guidelines.

Properties of Elements

Property

Default

Element

Description

Name

A default name

All

Identifies the element.

Qualified Name

Namespace :: Name

All

Identifies the element uniquely.

A component or type's name is prefixed with the qualified name of the package that contains it.

A part or port's name is prefixed with the qualified name of the component that owns it.

Work Items

0 associated

All

The number of work items associated with this element. To associate work items, see How to: Link from Model Elements to Work Items.

Description

(none)

All

You can make general notes about the element here.

Color

(default for the type)

Component, Part, Delegation, Part assembly

The color of the shape. Unlike other properties, this is the color of the shape rather than the model element that the shape displays.

Is Indirectly Instantiated

True

Component

The component exists only as a design artifact. At run time, only its parts exist.

Is Abstract

False

Component

The component definition can be used only as a generalization from which other components can be specialized.

Visibility

Public

Component, Part, Port

Public - globally visible.

Package - visible within the package.

Private - visible within the owning component.

Protected - visible to components derived from the owner.

Type

Type on creation

Part

Port

The type of a part is a component or class.

The type of a Port is an interface.

Multiplicity

1

Part

Port

Indicates how many instances of the specified type form part of the parent component.

1 - exactly one.

0..1 - one or none.

* - a collection of any number.

n..m - a collection of from n to m instances.

Is Behavior

False

Port

If true, messages to this port are handled by activities or operations that are described as part of the component, instead of its parts.

Is Service

False

Port

If true, this port is part of the published interface of this component.

LinkedPackage

Model

Diagram
