Part properties

Chapter 4 Building Structural Diagrams

Part properties

You can modify an object's properties from its property sheet. To open a part property sheet, double-click its diagram symbol or its entry in the Browser. The following sections detail the property sheet tabs that contain the properties most commonly entered for parts.

The General tab contains the following properties:

Property	Description
Parent	Specifies the parent object.
Name	The name of the item which should be clear and meaningful, and should convey the item's purpose to non-technical users.
Code	Specifies the technical name of the object, which is used for generating code or scripts.
Comment	Descriptive comment for the object.
Stereotype	Extends the semantics of the object beyond the core UML definition.
Visibility	Specifies the visibility of the object, how it is seen outside its enclosing namespace. You can choose between: Private – only to the object itself Protected – only to the object and its inherited objects Package – to all objects contained within the same package Public – to all objects (option by default)
Data type	Specifies a classifier as a data type.
Multiplicity	Specifies the number of instances of the part. If the multiplicity is a range of values, it means that the number of parts can vary at run time. You can choose between: * – none to unlimited 0..* – zero to unlimited 0..1 – zero or one 1..* – one to unlimited 1..1 – exactly one
Composition	Specifies the nature of the association with the parent object. If this option is selected, it is a composition and if not, an aggregation.
