An object-oriented framework for the hadronic Monte-Carlo event generators

We advocate the development of an object-oriented framework for the hadronic Monte-Carlo (MC) event generators. The hadronic MC user and developer requirements are discussed as well as the hadronic model commonalities. It is argued that the development of a framework is in favour of taking into account of model commonalities since common means are stable and can be developed only at once. Such framework can provide different possibilities to have user session more convenient and productive, e.g., an easy access and edition of any model parameter, substitution of the model components by the alternative model components without changing the code, customized output, which offers either full information about history of generated event or specific information about reaction final state, etc. Such framework can indeed increase the productivity of a hadronic model developer, particularly, due to the formalization of the hadronic model component structure and model component collaborations. The framework based on the component approach opens a way to organize a library of the hadronic model components, which can be considered as the pool of hadronic model building blocks. Basic features, code structure and working examples of the first framework version for the hadronic MC models, which has been built as the starting point, are shortly explained
