Inheritance of Automata Classes Using Dynamic Programming Languages (using Ruby as an Example)

This paper analyzed two libraries for implementation of automata in dynamic languages. The comparison has been made based on modifying the functionality of the Restful-authentication plugin for Ruby on Rails framework. These libraries allow transferring a graphical model into a source code. Moreover library developed by the authors of the paper provide a method for creation of state groups which reduces the number of transitions required to implement the automaton in the code. Also this library preserved the hierarchy of the parent automata after inheritance. Using developed library it is possible to perform a reverse engineering and restore the original graphical model from the source code.
