Aspect-oriented programming (AOP) addresses those issues by extending the OO approach even further. Many developers who are interested in AOP - especially in AspectJ, an open source extension of Java programming language that explicitly supports the AOP approach. Yet, although AspectJ is included with Eclipse, an increasingly popular open source IDE for Java, to find practical ways and non-theoretical to learn the language and other AOP tools and techniques has become a real problem. Until now. The AspectJ Cookbook offers a hands-on solution - in fact, several - with a variety of code recipes for solving day-to-day design and coding problems using AOP's unique approach. Without AOP, programmers must stitch yarn by hand. The AspectJ Cookbook shows readers why, and how common Java development problems can be solved by using AOP techniques. With a format that is popular problem-solution-our discussion, this book presents real world examples to demonstrate that AOP is more than just a concept, but rather a process of development which will benefit users directly and visible. If you are interested in how AOP is changing the way software is developed, and how you can use AspectJ to make code more modular, easier to develop, maintain, develop and deploy, this is a book that really delivers.
