IntelliJ IDEA 14.0.0 Web Help

Viewing Changes as Diagram

For the modules under version control, you can usually view the list of changed files in the Changes tool window. If you want to evaluate how your changes affect the model, use UML Class diagram. This view presents the complete picture of changes, including relationships between the modified classes.

For this purpose, IntelliJ IDEA provides the action Show changed classes, which is available from the editor, Project tool window, and the Local tab of the Changes tool window.

Moreover, IntelliJ IDEA helps you analyze how the changes affect a model across revisions, and provides the action Compare all classes from revision on UML.

Changes in Class diagram are color-coded:

  • Green for added elements.
  • Gray for deleted elements.
  • Blue for modified elements.
