Figure 9-2
Complete class specification with all three compartments
Name compartment
In Figure 9-2, the name compartment occupies the top section of the class box. The name
compartment holds the class name, an optional stereotype, and optional properties. The
name is located in the center of the compartment. The stereotype (>) may be used to
limit the role of the class in the model and is placed at the top of the compartment.
Common examples of class stereotypes include , based on the Factory design
pattern, and , for Java interfaces or for user interfaces.
Properties use the constraint notation { } and are placed in the bottom-right corner of
the compartment. Properties are basically constraints used to clarify the intent in defining
the model element. Properties can be used to document the status of a class under development
or for designations such as abstract and concrete.
Attribute compartment
In Figure 9-2, the attribute compartment occupies the middle section of the class box.
The attribute compartment simply lists the attribute specifications for the class using the
notation presented earlier in “Modeling an Attribute.” The order of the attributes does not
matter.
