我正在使用加载了 Cygwin 的普通 Python 2.7
我希望能够生成一个调用顶级函数的线程子类,并且顶级函数生成调用子级函数的单独线程。这是伪代码
import threading
#!/usr/bin/python
import threading
class Server(threading.Thread):
def __init__(self, threadID, target):
self.__threadID = threadID
self.__target = target
threading.Thread.__init__(self)
# Function called when the thread's start() function is called
def run(self):
self.target()
pass
# This is the top level function called by other objects
def reboot(self):
# I want this function to spawn two threads
# - First thread calls the __powerDown() function
# - Secod thread calls the __powerUp() function, and pends
# until __powerDown() thread finishes
pass
def __powerDown(self):
# What to put here?
pass
def __powerUp(self):
# What to put here?
pass
__threadID = ''
__target = None
# Code calling above code
server = Server(123, reboot) # Will this work?
最佳答案
类似这样的吗?
import threading
class Server(threading.Thread):
# some code
# This is the top level function called by other objects
def reboot(self):
# perhaps add a lock
if not hasattr(self, "_down"):
self._down = threading.Thread(target=self.__powerDown)
self._down.start()
up = threading.Thread(target=self.__powerUp)
up.start()
def __powerUp(self):
if not hasattr(self, "_down"):
return
self._down.join()
# do something
del self._down
关于python - 如何在Python中同一对象的另一个线程中生成一个线程?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/18989472/
