Ira Forman, IBM: Dr. Ira R. Forman works for IBM in Austin. As a member of IBM?s Object Technology Products Group, which produced the SOMobjects Toolkit, he worked on the SOM Metaclass Framework. He started working in the area of object-oriented programming in 1984, when he worked at ITT Programming Technology Center. Forman received his Ph.D. in Computer Science from the University of Maryland, where he studied under Harlan Mills. Forman?s specialties are object-oriented programming, distributed systems, and object composition. He is the coauthor of two books: "Interacting Processes: A Multiparty Approach to Coordinated Distributed Programming" and "Putting Metaclasses to Work: A New Dimension in Object-Oriented Programming."
Nate Forman, Ticom Geomatics: Nate Forman works for Ticom Geomatics where he designs and programs application frameworks for their products. His specialties are patterns and object-oriented programming. Forman holds a MSE in Software Engineering from the University of Texas at Austin and a BS in Computer Science from the College of Engineering at Cornell University.
Tutorial number: 12
The use of reflection is an important technique for
improving program flexibility and programmer productivity.
Reflection facilitates development
of programs that are easily adapted to requirement changes.
This property of reflection imples better code reusability as a corollary.
With reflection one can develop software engineering tools
that examine or produce code. Reflection facilitates testing
and problem determination by facilitating the automation of
more tedious tasks.
The Java programming language contains a highly
effective reflection facility. The tutorial explains the
concept of reflection, the Java metaobjects (including both
introspective and intercessional interfaces), the proxy class,
and dynamic compilation and class loading. The limits of
Java reflection are addressed in the context of what reflection
is capable of in general. In addition, the tutorial demonstrates
the efficacy of the Java reflection facility for solving practical
problems. Such problems include: program/application testing,
generation of code, inspection of code, and use of dynamic class
loading in a framework for application extension. The last topic
covered will be the performance impact of using reflection.
This tutorial inspired by the book "Java Reflection in Action"
(Manning 2004), which also provides supplementary material for
the tutorial.
Intermediate: Attendees should be competent Java programmers
