Abstract: For many applications, most code is not devoted to implementing
the primary input-output functionality but instead addresses other concerns,
such as reliability, availability, responsiveness, performance, security,
and manageability. Conventional programming practice requires the programmer
to keep all these other ilities in mind while coding and to explicitly
invoke behavior at exactly the right places to achieve them.
Aspect-Oriented Programming (AOP) is an emerging technology for allowing
the separate specification and coding of multiple concerns, while nevertheless
providing mechanisms to automatically meld these separate expressions
into working programs. In this talk I will present a pair of AOP systems,
our past work on the Object Infrastructure Framework (OIF) and our current
work on event-based quantification, and provide some observations on the
distinguishing characteristics of AOP technology.
OIF is a distributed object technology that implements separate concerns
as dynamic wrappers on object components. Interesting elements of OIF
include its mechanisms for application and aspect communication, its dynamic
nature, and its language for expressing where aspects apply to base code.
I will also describe our initial work on event-based quantification, an
attempt to map directed and widely the interesting properties of programs
into transformations that realize those properties.
About the Speaker: Robert E. Filman is a Senior Scientist at the Research Institute for Advanced Computer Science (RAICS) at NASA Ames Research Center, working on frameworks for developing distributed applications. Prior to coming to NASA in May 1999, Dr. Filman worked in the research groups of Lockheed Martin Missiles and Space, IntelliCorp, and Hewlett-Packard Laboratories, and on the faculty of the Computer Science Department at Indiana University, Bloomington. He is Editor-in-Chief of IEEE Internet Computing and is on the editorial boards of the Journal of Software Maintenance and Evolution and the International Journal of Artificial Intelligence Tools. He is the author (with Daniel P. Friedman) of Coordinated Computing: Tools and Techniques for Distributed Software (McGraw-Hill), and is currently editing the book Aspect Oriented Software Development with Mehmet Aksit, Siobhan Clarke, and Tzilla Elrad. He has worked and published in the areas of software engineering, distributed computing, network security, programming languages, artificial intelligence, and human-machine interface. Dr. Filman received his B. S. (Mathematics), M.S. (Computer Science) and Ph. D. (Computer Science) from Stanford University.
