Analyze class diagram

tip

You can press Ctrl+F12 on the element to view a list of diagram elements and navigate between them.

To see the list of methods, fields, and other code elements, select the appropriate icon on the diagram toolbar located on top of the diagram editor.

The lists are displayed based on the selected visibility level, which you can change. For example, to view protected methods, click on the diagram toolbar and select protected from the list. IntelliJ IDEA displays members with visibility not less than protected, such as public, package local, and protected ones. The protected methods are displayed with modifier icons next to them.

You can click the icon to see class dependencies. IntelliJ IDEA follows the UML conventions in showing relationships between the classes.

When you click through classes in the graph, IntelliJ IDEA greys out classes that do not reside in the same package. This might be helpful, when you generate a diagram on a package that contains inner packages.

To save the diagram as a file, right-click the diagram editor and from the context menu, select Save UML Diagram.

Manage class diagram

When working with diagrams, use the context menu in the diagram editor to perform different tasks. You can view members of the class, add new, delete the existing ones, see implementations, check parent classes, perform basic refactoring, add notes, and so on.

tip

You can select the icon on the diagram toolbar to draw relationship links between elements in your graph. To delete the existing links, select the ones you don't need and press Delete. IntelliJ IDEA will update the source code accordingly.
