| AspectJ is a simple and practical aspect-oriented extension to | |
| Java. With just a few new constructs, AspectJ provides support for | |
| modular implementation of a range of crosscutting concerns. | |
| </p><p> | |
| Adoption of AspectJ into an existing Java development project can be | |
| a straightforward and incremental task. One path is to begin by using | |
| only development aspects, going on to using production aspects and | |
| then reusable aspects after building up experience with | |
| AspectJ. Adoption can follow other paths as well. For example, some | |
| developers will benefit from using production aspects right | |
| away. Others may be able to write clean reusable aspects almost right | |
| away. | |
| </p><p> | |
| AspectJ enables both name-based and property based crosscutting. | |
| Aspects that use name-based crosscutting tend to affect a small | |
| number of other classes. But despite their small scale, they can | |
| often eliminate significant complexity compared to an ordinary Java | |
| implementation. Aspects that use property-based crosscutting can | |
| have small or large scale. | |
| </p><p> | |
| Using AspectJ results in clean well-modularized implementations of | |
| crosscutting concerns. When written as an AspectJ aspect the | |
| structure of a crosscutting concern is explicit and easy to | |
| understand. Aspects are also highly modular, making it possible to | |
| develop plug-and-play implementations of crosscutting | |
| functionality. | |
| </p><p> | |
| AspectJ provides more functionality than was covered by this short | |
| introduction. The next chapter, <a href="language.html">The AspectJ Language</a>, | |
| covers in detail more of the features of the AspectJ language. The | |
| following chapter, <a href="examples.html">Examples</a>, then presents some | |
| carefully chosen examples that show you how AspectJ might be used. We | |
| recommend that you read the next two chapters carefully before | |
| deciding to adopt AspectJ into a project. | |
