Write cleaner, easier-to-maintain applications with this code-intensive approach to using AspectJ Aspect-oriented programming (AOP) promises to increase the power of OO applications by modularizing functionality that cuts across classes (such as logging, transaction management, design patterns, and security). If your application has this type of functionality, you can benefit from using AspectJ, an AOP language that is a seamless extension to Java. In this code-intensive book, the authors present a detailed overview of the concepts of AOP and AspectJ, and take you step-by-step through the process of building an application. Along the way, you'll learn how to adopt AspectJ and use it with your current software development tools and processes. you'll also learn best practices for application design and documentation using UML. The perfect tool for Java and J2EE developers, this book also includes: Comprehensive description of the AspectJ language Best practices for refactoring your existing applications How to implement classic OO design patterns more cleanly with AspectJ Tips for debugging with AspectJ The companion Web site contains all sample code, the fully functional application created by the author, and links to relevant sites.
