Property Concept

When working with a class diagram, it is possible to activate or not the Property concept.

The Property concept is an abstraction of the common characteristics of an attribute and its accessor.

This concept occurs in two contexts :

• In an interface, a property is an abstraction of abstract accessors.
• In a class, a property is either an abstraction of an attribute and its accessors, or an abstraction of abstract accessors.

When activating the property concept, attributes and accessors are represented as a single member of a classifier (class or interface) : a property.

When the property concept is not activated, attributes and accessors are displayed as separated members of the classifier.
