Object Life-Cycle Management in a Highly Flexible Middleware System

Abstract. This paper describes the object life-cycle management in the Dinopolis middleware system. Advanced object composition is used to support adaptability and extensibility of the running system. Such a high degree of flexibility requires mechanisms to keep objects and the entire system in a consistent state. We show that a fine-grained definition of the object life-cycle helps controlling objects in a highly flexible fashion. Moreover, we discuss how the life-cycle of composed objects can be exploited to model different dynamic scenarios found in distributed, dynamically changing environments.
