Aspect-oriented software design (ASOD), which follows the Java philosophyof "write once, run anywhere", is a new way of thinking about programconstruction. It is a rapidly growing and evolving programming methodologythat some feel may eventually replace object-orientation as the dominantprogramming paradigm. The first public release of the AspectJ programminglanguage was in 1998 and has been gaining momentum ever since. This book isan introduction to AOP with AspectJ and Eclipse and shows how to create aproductive AO development environment by using the AspectJ DevelopmentTools for Eclipse (AJDT). Tools have an important role to play in learningaspect-orientation (AO) and Eclipse tools help Java developers betterunderstand AOP. In fact the growing interest in AOP can be attributed to thebetter available tools and this book teaches the reader everything they need tounderstand AOP and apply it successfully to their own projects.

Features + Benefits
The definitive (and only) introduction to Aspect-Oriented Programming (AOP) using Eclipse and ASpectJ.
° Author team is made up of the lead developers of AspectJ Development Tools(AJDT)
° AOP and AspectJ are rapidly growing and evolving along with Eclipse
° The first book to present a complete package of a productive development environment for AOP
Backcover
Now every Java developer can leverage the immense power of AOP 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.
No AOP or Eclipse experience necessary!
Install and configure both Eclipse and the AspectJ Development Tools (AJDT)
Discover how AOP can modularize and optimize everything from error checking to performance
Craft new AspectJ applications and incorporate AOP capabilities into existing systems
Build, debug, and document AspectJ applications
Understand crucial AOP concepts, such as join points, pointcuts, advice, and inter-type declarations
Master advanced techniques: Aspect libraries, linking with compiled .class files, visualization, aspect-oriented design, and more
The accompanying website, www.awprofessional.com/title/0321245873, is full of samples, examples, and source code to help you start writing Java-based AOP software today.

Aspect-oriented software design (ASOD), which follows the Java philosophy
of write once, run anywhere, is a new way of thinking about program
construction. It is a rapidly growing and evolving programming methodology
that some feel may eventually replace object-orientation as the dominant
programming paradigm. The first public release of the AspectJ programming
language was in 1998 and has been gaining momentum ever since. This book is
an introduction to AOP with AspectJ and Eclipse and shows how to create a
productive AO development environment by using the AspectJ Development
Tools for Eclipse (AJDT). Tools have an important role to play in learning
aspect-orientation (AO) and Eclipse tools help Java developers better
understand AOP. In fact the growing interest in AOP can be attributed to the
better available tools and this book teaches the reader everything they need to
understand AOP and apply it successfully to their own projects.
