Viewing classes using compartment notation
Viewing classes using compartment
notation
Ways to show classes FrameWork provides two alternative notations for classes. Box
notation, which you’ve been using to build your Java class
diagram, displays a class as a box with the class name. The other
notation, called compartment notation, shows a class as a set of
three compartments and complies with the OMG UML 1.1
suggested standard.
Compartment notation When you view a class in compartment notation:

■ The top compartment shows the class name, which can be
edited in place, just as it can in box notation.
■ The middle compartment lists the attributes defined for the
class. Each attribute name is preceded by a graphic indicating
the attribute visibility and followed by the attribute data type.
■ The bottom compartment lists the operations defined for the
class. Each operation name is preceded by a graphic indicating
the operation visibility and followed by the operation return
type.
Note
Visibility is the property of an object that specifies the level
of access other objects have to it.
So far, you’ve viewed classes only in box notation. Now you’ll view
them in compartment notation.
