Class structure diagrams

The aim of this automatic diagram is to show how a class is made, what it consists of, what it inherits from and what embarks it.

Applicable elements

Class structure diagrams can be created on any Classifier.

Contents

• Class C itself.

• The public attributes of C.

• The classes to which C has an association.

• C’s parent class if this exists.

• The interfaces implemented by C if these exist.

• The classes which have composition or aggregation associations to .

Layout

• Class C is positioned in the center of the diagram.

• The classes linked to C through associations leaving from C:

  • are placed to the right of C.

  • are viewed in “simple” mode.

  • are exactly the same size and are aligned vertically.

• The classes linked to C through compositions or aggregations arriving in C:

  • are placed to the left of C.

  • are viewed in “simple” mode.

  • are exactly the same size and are aligned vertically.

• C’s parent classes and interface:

  • are placed above C.

  • are viewed in “simple” mode.

  • are exactly the same size and are aligned horizontally.

• Auto-associations are placed below and to the right of C.

• All associations (other than auto-associations) are represented horizontally by a single straight line (no bends), and are regularly spaced vertically.

• Class C is resized vertically to cover all the associations.

Note: All elements present in this diagram have a specific associated style.
