Abstract
Abstract A method, apparatus, and article of manufacture for modeling object-oriented systems includes an object modeling tool that defines methods and event transitions in an object-oriented system and generates an executable program that exhibits the behavior of the object-oriented system and interfaces with the object-oriented system. The object modeling tool further translates the event transitions to an execution language, wraps methods written in the target language, wraps event transitions corresponding to an event, and gathers one or more wrapped events and methods into an executable program.
