include Macro

[Ceset]

Hi guys.

Everytime i create a class header like

#IFNDEF BLAH_H
#DEFINE BLAH_H

#include "foo"
#include "bar"

class Blah{

};

#ENDIF 

And if i add it like #include "blah.h", i also add foo and bar classes and see the functions they provide. Is there a way to prevent this.

Thanks in advance.

Not a good way, no. #include is a glorified copy/paste -- it's like you're copy/pasting the header into the file that includes it.

The best way is to simply not include foo/bar in the header.

If i need to use foo and bar classes' functions inside Blah, how else i can add them? An example maybe.

Sorry if i misunderstood.

If you don't need the full class you can forward declare them and avoid the include.

If you do need the full class then you'll have to include them. And I guess just live with the fact that they'll also be included in anything that includes your header. =/

So simply put, there is no way :)

Thanks for all the answers anyway. Helped a lot.
