ECO (Extender and Class Oriented) extends the object-oriented paradigm with features that make easy handling graphs. Its purpose is to simplify the description of systems managing complex combinatorial structures with properties that change dynamically. Its main area of application is graph managment, but ECO is not only related to graphs. An extension of C++ (we call it ECO C++) and a precompiler for such extension makes ECO concepts implementable and easy to use.
ECO based systems are more flexible and extensible than systems based on the usual object-oriented paradigm.
Designing software with ECO is more natural and leads to better understandable code. ECO C++ primitives do not introduce computational overhead.

Why extending the usual object-oriented paradigm?

What's wrong with the usual object-oriented paradigm? Examples of problems arising in the usage of existing libraries in handling graphs are given.

Extensions to the usual object-oriented paradigm are described.

Description of an extension of C++. New linguistic primitives allow a clear and simple implementation of ECO concepts.

Description of our precompiler for ECO C++. It works with the GNU G++ compiler.
