Re: cout<< or .toString() in Objective-c?

[Laszlo Gulyas]

Hi Ralf,

Thanks for the note. I am not sure, however, wether I was clear enough.
What I would like to do is to have a method or tool that can be applied
to an arbitrary object and can dump information about on the given 
object to a file.

E.g., in Java you can do the following:

        Object arbitraryObject;
        System.out.println(arbitraryObject); // calls arbitraryObject.toString()

What is not clear in your example is that what method to call on my object
to dump itself to myStream in your example.

Thanks, Gulya
