Eclipse AspectJ - Aspect-Oriented Programming with AspectJ and the Eclipse AspectJ Development Tools

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.
