A filter object framework for MICO

Abstract

Filtered delivery model of message passing in an object-oriented distributed computing environment facilitates separation of message control from message processing in a transparent manner. In this model, special objects called filter objects have the ability to filter messages in transit and perform intermediate actions. We present the design and implementation of the message filtering model for transparent dynamically pluggable filter objects for MICO, an open-source CORBA implementation. For implementing the filtering framework, enhancements to the MICO implementation model are proposed. A process for development of filter objects with related tool support has also been outlined. © Springer-Verlag Berlin Heidelberg 2002.
