象对静态方法和类所做的那样，只要防止程序员在静态字段中引用泛型类型，情况就会好很多。
It would be much better to simply prevent the programmer from referring to generic types in static fields, as is done in the case of static methods and classes.
时序图利用建模系统的逻辑流程，详细描述了应用程序中各个类之间交互的系统方法，并且允许你对方法的入口和出口进行分类。

解决类可视性问题的惟一方法是确保所有的应用程序类都可见。
The only way to resolve class visibility problems is to ensure that all the application classes are visible.
对程序中的某些类和方法，我需要了解它们被调用次数，各自平均执行时间和整体平均时间
For certain classes and methods in my application I want to see the invocation counts, the average self execution time and the average wall clock time.
它的检测方法本质上是重新定义程序执行中的大多数类和方法，结果必然会明显减缓程序执行速度。
It's instrumentation approach will essentially redefine most of the classes and methods that your application is executing, and as a result is likely to slow down your application significantly.
