Chapter 18. Show Usages, Readers or Writers

To search where a function, variable, class, module or any other entity is used, hover over it's name while holding down the Ctrl key and select Show Usages.

For variables, ports or parameters, you also have the option to Show Readers or Show Writers.

The results are presented in the Search View.

For variables, ports or parameters, matches are decorated to indicate the access type: read, write or read/write (for example i++).

Tip: You can also place the editor cursor on the identifier, right click and choose Show > Usages.

Tip: When searching for usages of a virtual function, by default you also see the usages of functions overriden by it.

You may choose to hide such matches using the Hide References to Overridden filter.

Tip: When searching for usages of a class field whose enclosing scope is a specialized class, the usages of different specialization are not shown.

Check All specializations filter to see all usages, regardless of their specialization.

The same applies for functions or tasks and its arguments.

Tip: When searching for usages of a class field, calls to the field's getter and setter functions are also shown. Getter and setter functions are within the class or any of its children and have a single statement inside their body:

  • for setters - an assignment of the searched field

  • for getters - a return of the searched field

You may choose to hide such matches using the Hide References to Getter/Setter filter.

Tip: You can also search for references from the Search Dialog (Ctrl+H) .
