reset

问题 I am trying to let some code fire after my FileSystemWatcher hasn't received any changes for more then 5 minutes. My current approach is to call a await Task.Delay(); after a change, hoping the user is done by then. This obviously is not the way to go. So my question: How to reset a Task.Delay() after a event fired? 回答1: You can't "reset" a Task.Delay , but you can reset a timer which makes it an ideal candidate to solve this problem. Here's an example: private System.Threading.Timer timer;

问题 Hi i have a strange problem with a WordPress plugin that i am writing, but this isnt about WordPress per se and more to do with PHP so please read on so I can explain.

问题 I need a timer in Python which i can reset (timer.reset()). I already have a periodic timer. Is there a library with such a timer? class MyTimer(threading.Timer): def __init__(self, t): threading.Thread.__init__(self) self.__event = threading.Event() self.__stop_event = threading.Event() self.__intervall = t def run(self): while not self.__stop_event.wait(self.__intervall): self.__event.set() def clear(self): self.__event.clear() def is_present(self): return self.__event.is_set() def cancel

问题 I recently wanted to, as I thought, update my code on the remote git repository. I didn't realize it's not even committed yet. I did create some errors, so I wanted to reset the branch to its previous state. As you may expect, I used git reset --hard . Well, everything (the whole project) has been gone ever since; except the .gitignore files/folders, of course. I've been wondering, is there any way to undo that? The only steps I did: git add . # Here I realized there is a bug in what I did #
