Hello guys,
I am quite unsure about what I should or should not include, I am more interested into best practices rather than definitions. I am converting my project to IWYU system.
My code uses Navigation headers, however I noticed all these headers are included in NavigationSystem which I use too. Should I include only NavigationSystem or should i explicitly list there all headers?
Good example is also AIController.h, it includes UObjectGlobals.h, so if I have child of AIController.h with FObjectInitializer constructor I don’t need to include UObjectGlobals.h in my cpp file.
Also, what are your tips and tricks when it comes to managing includes?
Include only the bare minimum required to compile, anything more is just adding compile time.
Are you using the methods of an object? Include it.
Are you just storing a pointer to that object? Forward declare it (if in a header file).
You also don’t want to rely on includes from other files, your code should be able to compile on its own. So with regard to your AIController example - I would include the UObjectGlobals.h as well just to be explicit that this code is using that class.
Thanks, thats valueable anwser. I think I will probably ignore includes for parent classes. So I will not be including AActor when I am sure that my parent is derived from AActor and so on.
