View code hierarchy

With AppCode, you can examine the hierarchy of types, method calls, and imports and explore the structure of the source files.

Build hierarchies

When built, a hierarchy can be immediately viewed and examined in the Hierarchy tool window. By default, every new built hierarchy overwrites the contents of the current tab. You can retain the current tab and have the next hierarchy built in a new one.

Build a type hierarchy

In the editor, position the caret at the desired class.
From the main menu, select Navigate | Type Hierarchy or just press Ctrl+H.

Different colors of elements stand for different scopes to which these files belong. For example, green by default is used for tests. For more information, refer to Associate scopes with colors.

Build a call hierarchy

Call hierarchies show callers or callees of a method or function.

Open a file in the editor and place the caret at the declaration or usage of the desired method.
From the main menu, select Navigate | Call Hierarchy or press Ctrl+Alt+H.

Build a hierarchy of imports

Imports hierarchies show where the current file is included and track all files included in the current file.

Open the file in the editor or select it in the Project tool window.
From the main menu, select Navigate | Imports Hierarchy.

Retain a hierarchy tab

In the Hierarchy tool window, click the Pin Tab button on the toolbar.

View hierarchies

Open the Hierarchy tool window

Make sure, you have already built hierarchies to show, see Building hierarchies above.
Select View | Tool Windows | Hierarchy from the main menu.

Navigate between the tabs

Click the currently displayed tab and select the next one to display from the list.

Toggle between views

With AppCode, you can build and explore ascending or descending hierarchies, that is, callee or caller methods, parent or children classes, and so on.
Click or to show caller methods or callee methods respectively.

Item	Description	Available In
	Shows both the parent and child classes of the selected class, which is marked with an arrow in the tree of results.	Type hierarchies
	Depending on the hierarchy type: Type hierarchies: shows the hierarchy of each supertype of the current type. Call hierarchies: shows the callers of the selected method. Import hierarchies: shows the files where the current file is included.	All hierarchies
	Depending on the hierarchy type: Class hierarchies: shows all classes that extend the selected type. Call hierarchies: shows the callees of the selected method. Import hierarchies: shows the files that include the current file.	All hierarchies
	Sorts all elements within a tree alphabetically.	Type hierarchies Call hierarchies
Scope	Use this list to limit the scope of the current hierarchy: Project: traces usages of the method across the project. Test: traces usages of the method across the test classes. All: traces usages of the method across the project and the libraries. This class: limits the scope to the current class. In addition to the preconfigured scopes, you can define your own one. To define a scope, select Configure from the list and define the required scope in the Scopes dialog.	Call hierarchies
