一个AOP工具连接点模型的表达方式决定了可用的连接点粒度，以及连接点如何匹配。
The expressiveness of an AOP tool's join point model determines the granularity of the join points available, and how those join points are matched.
下一步，我将快速地回顾AOP的连接点模型的基本内容，并说明它从元数据增强中可以获得哪些好处。
Next, I'll quickly review the basics of AOP's join point model and explain where it would benefit from metadata fortification.
位于每个AOP工具核心的是连接点模型，它提供了一种机制，可以识别出在哪里发生了横切。
At the heart of each of the AOP tools is a join point model, which provides a means of identifying where the crosscutting is happening.
连接点模型是AOP中最基本和最独特的概念，它定义了系统中哪个连接点是公开的，以及如何捕获它们。
The join point model, the most fundamental and distinguishing concept in AOP, defines which join points in a system are exposed and how they are captured.
AspectJ和AspectWerkz的连接点模型差不多完全融合，而且已经成为最近的合并的关键促进者之一。
