With AspectJ, Java developers can leverage the breakthrough power of Aspect-Oriented Programming (AOP) using a language they already know, within the comfortable, highly productive Eclipse development environment. In this book, AspectJ's lead developers help you master AOP's essential principles and techniques, as you use them to address your toughest software quality, productivity, and maintenance challenges. AOP improves the modularity of programs, making the code much closer to the design. It can dramatically reduce the time taken to implement common features and functions, improve quality, integrate plain-old Java objects with systems and services, create simpler, more reusable components, and much more besides.Drawing on their experience as tool developers, programmers, and mentors, the authors cover every facet of AOP development with AspectJ and Eclipse, from creating new projects through extending and documenting full-fledged applications. You'll find an authoritative tutorial covering the entire AspectJ language, a complete API reference, and realistic guidance on adopting AspectJ in your organization.
