I'd like to set a set of breakpoints in a couple of tight loops.. but I just want them to fire after a given event occurs.
我想在几个紧密循环中设置一组断点..但我只是希望它们在给定事件发生后触发。
The problem lies in the fact that all those breakpoints are defined in a very low level module, so they can't know when that high level event is raised.
问题在于所有这些断点都是在非常低级别的模块中定义的，因此他们无法知道何时引发高级别事件。
It'd be perfect if I could set a special conditional breakpoint in the high level code, such that after that breakpoint condition was met it would, from that moment on, start firing any other breakpoints found in the program (I don't particularly care for that high level breakpoint, though).
如果我可以在高级代码中设置一个特殊的条件断点，那将是完美的，这样在满足断点条件之后，从那一刻起，它将开始触发程序中找到的任何其他断点（我不特别尽管如此，关心那个高级断点。
Is there any way to accomplish something like this? If not, how to circumvent this limitation? The only way that comes to mind would be to define a temporary singleton to keep state and have my low level breakpoints depend on that singleton's flag.
有没有办法完成这样的事情？如果没有，如何规避这种限制？想到的唯一方法是定义一个临时单例以保持状态，并让我的低级别断点依赖于该单例的标志。

You can make creative use of assertions, but they are disabled in Eclipse by default.
您可以创造性地使用断言，但默认情况下它们在Eclipse中被禁用。
Here's a good link explaining how to enable assertions: http://www.cis.upenn.edu/~matuszek/cit594-2004/Pages/eclipse-faq.html#assert

Eclipse has a very useful mechanism for breaking on Exceptions. It's a different kind of breakpoint, which is triggered when the exception is thrown, regardless of how (and if) it is caught. If you are using assertions, I highly recommend setting a breakpoint on assertion failures when debugging your code.
Eclipse有一个非常有用的机制来打破异常。它是一种不同类型的断点，它在抛出异常时触发，无论它是如何（以及如果）被捕获的。如果您正在使用断言，我强烈建议在调试代码时在断言失败时设置断点。

You're asking several different questions here.

In answer to "Q: can I set a breakpoint that triggers when some event occurs", you might want to look at "watch points":

The same article discusses a possible answer to another of your questions: "Q: ... after that breakpoint condition was met it would, from that moment on, start firing other breakpoints..."

Look for "breakpoint properties", in the same article.
