When Object Oriented programming (OO) first appeared, it was a
revelation. OO gave developers the ability to create software that was
more flexible and robust, but as time went on and applications became
more sophisticated, too, certain areas of "traditional" OO architectures
were found wanting. Aspect-oriented programming (AOP) addresses those
issues by extending the OO approach even further.Many developers are
interested in AOP--especially in AspectJ, the open source extension of
the Java programming language that explicitly supports the AOP approach.
Yet, although AspectJ is included with Eclipse, the increasingly popular
open source IDE for Java, finding a practical and non-theoretical way to
learn this language and other AOP tools and techniques has been a real
problem.Until now. The AspectJ Cookbook offers a hands-on solution--in
fact, several--with a wide variety of code recipes for solving
day-to-day design and coding problems using AOP's unique approach.AOP
allows the global properties of a program to determine how it's compiled
into an executable program. Before AOP, important program design
decisions were difficult to capture in actual code. Instead, the
implementation of those design decisions--known as "aspects"--were
scattered throughout, resulting in "tangled" code that was hard to
develop and maintain. AOP has been compared to the manufacturing of
cloth, in which threads are automatically interwoven. Without AOP,
programmers must stitch the threads by hand.The AspectJ Cookbook shows
readers why, and how, common Java development problems can be solved by
using AOP techniques. With our popular problem-solution-discussion
format, the book presents real world examples to demonstrate that AOP is
more than just a concept; it's a development process that will benefit
users in an immediate and visible manner.If you're 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, evolve and
deploy, this is the book that really delivers.
