Source code hierarchy
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
Select the desired type or interface in the editor.
From the main menu, select Navigate | Type Hierarchy or just press Ctrl+H.
Build a call hierarchy
Open the file in the editor and place the caret at the declaration or usage of the desired method or a function.
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 on the toolbar.
Viewing 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.
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 or to show caller methods or callee methods respectively.
