Reference documentation

[Michele Bert]

I am starting my first small application with GNUstep (just to practice), and I have already a question: where can I find a reference guide to a gnustep class?

For example, I am using an NSTableView, so I remember I have to implement two method in a controller object to get the number of rows and to get the value of a specific column/row; something like:

- (int) getRowCount;

- (id) getValueAtcolumn: (NSTableColumn*)collumn row:(NSInteger) row;

But I do not remember (of cource) the exact definition. Are there any reference guide (on the net, or in the gnustep installed package) where I can search this kind of details?

Thanks
