ABSTRACT:
A system for object oriented message filtering for selectively transferring a message between a client task and one or more server tasks for preprocessing, processing, and postprocessing comprises an object database having a filter object memory, an object management unit, a message transaction unit, and a locking unit. The object management unit creates a port object and one or more associated target message objects. The object management unit selectively creates one or more filter objects associated with a target message object, and selectively associates a preprocessor message object, a postprocessor message object, or both a preprocessor message object and a postprocessor message object with each filter object. The message transaction unit selectively routes a message sent by a client task and directed to a target message object to one or more associated preprocessor message objects prior to delivering the message to the target message object. After delivery to the target message object, the message transaction unit selectively routes the message to one or more associated postprocessor message objects. Server tasks receive messages from port objects associated with preprocessor message objects, target message objects, and postprocessor message objects, facilitating preprocessing, processing, and postprocessing operations.
