Use hierarchy view

Opening a type hierarchy on a Java element

There are six ways to open a type hierarchy. Select a java element in a Java view and:

Type Hierarchy view

This view shows the hierarchy of a type. The Type Hierarchy view consists of two panes:

Type Hierarchy View

Type Hierarchy tree pane toolbar buttons

Member list pane toolbar buttons

The member list pane displays the members of the currently selected type in the type hierarchy tree pane.

J2EE Hierarchy view

The J2EE Hierarchy view displays the model objects for each of your J2EE projects. This view does not display the actual underlying resources. It only displays the model objects that are represented in these resources. Therefore, not all actions are available from the J2EE Hierarchy view, and file-based options (like those available from the Project Navigator view) do not apply. For example, because the Tasks Filter works off of the file system, it does not work in the J2EE Hierarchy view.

You should use this view to view your J2EE deployment descriptors with their content. You can easily view an enterprise application project and see all of the modules associated with it. Within each module, you will be able to see the objects that are represented in each module. By double-clicking on modules in the J2EE Hierarchy view, you can edit your descriptor files.

There are eight groups in the J2EE Hierarchy view. Each view represents a different part of an enterprise application:

Links view

The Links view (Window > Show View > Links) shows the files in your projects, the linkages between them and the characteristics of those linkages. This view helps you distinguish between different types of links, shows you the number of links to target files and indicates where documents have broken links or links to external files.

The Links view is like the J2EE Navigator view in that you can open files by double-clicking on the file icons it displays. Similarly, the J2EE Navigator view shows you a file system hierarchical view of your project and the Links view shows you the hierarchical relationship of your files, based on the links between them.

When files contain links to other files, they can be described as having parent-child relationships. When a file is in focus in the Links view, you can see the hierarchical relationships between it and the files to which it links. You can look at the parents (the files to the left) that contain links to the file in focus and the children (the files to the right) that are the targets of the links.

Hypertext links in HTML files are displayed as arrows between the files in the Links view. Hypertext links can be divided into different types. The Links view shown here displays examples of the most common kinds of links:
