Class AsyncNotifier

Initializes the async notifier. The only additional parameter is 'channel_map' which is the optional asyncore private map. See Notifier class for the meaning of the others parameters.

Parameters:

• watch_manager - Watch Manager.
• default_proc_fun - Default processing method. If None, a new instance of PrintAllEvents will be assigned.
• read_freq - if read_freq == 0, events are read asap, if read_freq is > 0, this thread sleeps max(0, read_freq - (timeout / 1000)) seconds. But if timeout is None it may be different because poll is blocking waiting for something to read.
• threshold - File descriptor will be read only if the accumulated size to read becomes >= threshold. If != 0, you likely want to use it in combination with an appropriate value for read_freq because without that you would keep looping without really reading anything and that until the amount of events to read is >= threshold. At least with read_freq set you might sleep.
• timeout - see read_freq above. If provided, it must be set in milliseconds. See https://docs.python.org/2/library/select.html#polling-objects

Overrides: object.__init__

When asyncore tells us we can read from the fd, we proceed processing events. This method can be overridden for handling a notification differently.
