Source code hierarchy

Last modified: 19 March 2022

With GoLand, you can examine the hierarchy of types, methods, and calls and explore the structure of source files.

Build hierarchies

  • Type hierarchies show what interfaces are implemented by the type and what types implement the interface.

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

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

  1. Select the desired type or interface in the editor.

  2. From the main menu, select Navigate | Type Hierarchy or just press Ctrl+H.

Build a call hierarchy

  2. From the main menu, select Navigate | Call Hierarchy or press Ctrl+Alt+H.

Retain a hierarchy tab

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

Viewing hierarchies

Open the Hierarchy tool window

  1. Make sure, you have already built hierarchies to show, see Building hierarchies above.

  2. 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.

Switch between callers and callees

  • With GoLand, you can build and explore ascending or descending hierarchies, that is, callee or caller methods, parent or children types, and so on.

    Click the Caller Hierarchy toolbar button or the Callee Hierarchy toolbar button to show caller methods or callee methods respectively.
