如何在Eclipse中的Class NOT一行设置断点？

我只想在一组特定的类中调用任何函数后开始调试。

是否可以实现这一点在Eclipse中？
或者我必须在每个要调试的类中的每个函数上设置断点？

Is it possible to achieve this in Eclipse ? or do I have to set a breakpoint on each function in each class I want to debug?

更新：

我没有问过如何在eclipse中设置断点。我想调试一个类，而不知道要调用哪个函数。

I didn't ask how to set a breakpoint in eclipse. I would like to debug a class without knowing which function is going to be called.

更新2：

（我将使我的问题更清楚）

(I am going to make my problem more clear)

我被要求修复应用程序中的错误（我没有实现）。我设法缩小相关类到这个bug。每个类都有超过30个功能的问题。而且我不知道调用哪些函数。所以我正在考虑是否可以在类本身设置一个断点，以便在调用此类中的函数后开始调试。

I was requested to fix a bug in an application (Which I didn't implement). I managed to narrow down the related classes to this bug. The problem each class has over 30 functions. And I don't know exactly which functions are invoked. So I was thinking if its possible to set a breakpoint somehow on the class itself in order to start debugging once a function within this class is invoked.

我会感谢任何帮助，
