Abstract

A software system has dynamic adaptability if it can adapt itself to dynamically changing runtime environments. This means that such a software system can change its own behavior depending on states of runtime environments in flexible way. We have proposed a software model with dynamic adoptability named DAS and its description language LEAD++. The DAS model is a reflective software model, and LEAD++ is an object-oriented reflective language based on Java. In this work, we apply our model to component-based software systems, and introduce dynamic adaptability into them by using LEAD++. The basic approaches are to change dynamically: the structure of component composition; and the inside behavior of each component, depending on the states of runtime environments
