The within pointcut is similar to this(), except that ajc detects it entirely at compile time (most pointcuts can discriminate based on run-time information).
除了ajc在编译时彻底检测 withinPointcut 以外（大多数Pointcut可以根据运行时信息区别开来）， withinPointcut类似于this()。
UIs for graphical selection and manipulation of pointcuts will benefit from a common set of heuristics that can turn selections and search results into pointcuts.

I'm not going to try to duplicate all that here, but I will give a brief introduction to what I see as the most important concepts: pointcuts, aspects, and advice.

The other AOP tools check to varying degrees the well-formedness of aspect declarations, but they offer no static checking of pointcuts, whether declared using annotations or XML.
其他AOP工具可以检查方面声明的合格程度，但是，不管是用注释还是用XML 声明，它们都没有提供切入点的静态检查。
