t.i.c._WakerPlus(_Waker) : class documentation

Part of twisted.internet.cfreactor View Source View In Hierarchy

The normal Twisted waker will simply wake up the main loop, which causes an iteration to run, which in turn causes PosixReactorBase.runUntilCurrent to get invoked.

CFReactor has a slightly different model of iteration, though: rather than have each iteration process the thread queue, then timed calls, then file descriptors, each callback is run as it is dispatched by the CFRunLoop observer which triggered it.

So this waker needs to not only unblock the loop, but also make sure the work gets done; so, it reschedules the invocation of runUntilCurrent to be immediate (0 seconds from now) even if there is no timed call work to do.

Method doRead Wake up the loop and force runUntilCurrent to run immediately in the next timed iteration.
def doRead(self): (source)
Wake up the loop and force runUntilCurrent to run immediately in the next timed iteration.
