如何在Jython中擴展Java TimerTask並將參數傳遞給它？

Question

我試圖擴展Jython中的TimerTask以讀取某些傳感器的數據，然後每隔一秒鐘通過網絡發送這些數據。爲了做到這一點，我需要將讀者和服務器對象（以及一些事件對象）傳遞給TimerTask對象。當我嘗試通過Timer.schedule的方法做它，我得到這個錯誤：

File "C:\Documents\src\iButtonHandler.py", line 61, in run 
TypeError: org.python.proxies.iButtonHandler$IButtonTimerTask$1(): expected 0 args; got 4 

我收集了Timer.schedule方法調用TimerTaskObject的run方法，但爲什麼沒有首先調用__init__？我也嘗試將這些參數添加到我的TimerTask的run方法中，但我得到了同樣的結果。

這裏是我的代碼：

class IButtonTimerTask(TimerTask): 

    def init(self, reader, server, enterPressed, runComplete): 
     self.__reader = reader 
     self.__server = server 
     self.__enterPressed = enterPressed 
     self.__runComplete = runComplete 

    def run(self): 
     iButtonData = self.__reader.getAllValues() 
     self.__server.sendData(iButtonData): 
     if self.__enterPressed.isSet(): 
      self.cancel() 
      self.__runComplete.set() 

class IButtonHandler(threading.Thread): 

    def __init__(self, port, container, enterPressedEvent, exitEvent): 

     threading.Thread.__init__(self, name='iButton Handler Thread') 
     print 'creating ibutton thread' 
     self.__container = container 
     self.__reader = IButtonContainerReader(self.__container) 
     self.__containerId = self.__reader.getID() 
     self.__server = MyServer(port, name=self.__containerId) 
     self.__enterPressed = enterPressedEvent 
     self.__exitEvent = exitEvent 
     self.__runComplete = threading.Event() 
     self.start() 


    def run(self): 
     print 'ibutton thread running' 
     if self.__server.listen(): 
      timer = Timer() 
      timer.schedule(IButtonTimerTask(self.__reader, self.__server, self.__enterPressed, self.__runComplete), 0, 1000) 

     self.__runComplete.wait() 
      print 'iButton handler %s exiting' %self.__containerId 
      timer.cancel() 
      self.shutDown() 
      return 

我看到，在直Java中你簡單地擴展TimerTask並在Timer.schedule方法調用new MyTimerTask(...)。我似乎無法使它在Jython中以這種方式工作。我究竟做錯了什麼？

謝謝你看看這個！

你init應該叫__init__：

class IButtonTimerTask(TimerTask): 

    def __init__(self, reader, server, enterPressed, runComplete):
