Hi all.

Can anyone give some good pointers or hyperlinks about how to 'extend' the
STL with my own datastructures?

For example, I'd like to add a disjoint set datastructure, but I don't know
how to use (derive from?) the std::iterator in my own class. Also, the stuff
with
allocators isn't entirely clear to me.

Does anybody know of any links which describe this sort of information about
the STL?

Thanks in advance,
Leon.

I can suggest a book: The C++ Standard Library A Tutorial and Reference
by Nicolai M. Josuttis. ISBN: 0-201-37926-0

Section 7.5.2 "User-Defined Iterators" tells you what you want to know
and provides example code.

Hi Leon,

I advice to study a good book on the STL. Personally I appreciate both
The C++ standard Library, A tutorial and reference by Josuttis
and
C++ templates The complete guide by Vandevoorde and Josuttis
very much. The first book will probably already get you there.

Cheers, Cees
