Composite and Inner Classifiers

A composite classifier is a class or an interface that contains other classes or interfaces (called inner classifiers). Inner classifiers are listed in the Browser as children of their composite classifier.

Inner classifiers can be displayed directly in the main class diagram, or in a additional class diagram specific to the composite classifier:

Note: You can display multiple composite classifiers in a composite structure diagram (see Composite Structure Diagrams).

Note: In previous versions of PowerDesigner, there was no composite classifier and inner classifiers used to appear at the same hierarchical level as their parent in the Browser tree view and in the list of classifiers.

• Creating Inner Classifiers
  You can create inner classifiers in a class or interface.
• Creating a Composite Classifier Diagram
  You may want to create a diagram to show the internal structure of a composite classifier. You can create a composite classifier diagram in any of the following ways:
