Dependency Viewer

View | Tool Windows | Dependency Viewer

The Dependency Viewer tool window displays the results of analyzing dependencies, backward and cyclic dependencies. It is available after you've run a dependency analysis (Analyze | Analyze Dependencies)

Panes of the dependency Viewer

The Dependency Viewer consists of the following panes:

  • Analyzed Code pane in the upper-left part of the tool window containing a tree view of your project's files and packages. Selecting a node (package or file), for which you want to find dependencies, populates the Parent Code pane.

  • Parent Code pane in the upper-right part of the tool window represents the classes your selection depends on. In addition to the other classes in project, these dependencies also include any classes in the libraries and test sources, if the corresponding view filter is enabled.

  • Usage pane in the lower-left part of the tool window is populated when you select an entry in the Parent Code pane.

    • For the dependencies analysis this pane contains the objects which your code is dependent on (that is, the code in the left pane uses them).

    • For the backward dependencies analysis, these are the objects that depend on your code (that is, they use something of the code in the left pane).

    • For the cyclic dependencies analysis this pane shows the objects which the analyzed code refers to and which, in turn, refer back to your code.
