Method _disconnectSelectable Utility function for disconnecting a selectable.

Inherited from _SignalReactorMixin (via PosixReactorBase):

Method startRunning Extend the base implementation in order to remember whether signal handlers should be installed later.
Method _reallyStartRunning Extend the base implementation by also installing signal handlers, if self._installSignalHandlers is true.

Inherited from ReactorBase (via PosixReactorBase):

Method installResolver Set the internal resolver to use to for name lookups.
Method doIteration Do one iteration over the readers and writers which have been added.
Method resolve Return a Deferred that will resolve a hostname.
Method crash See twisted.internet.interfaces.IReactorCore.crash.
Method sigInt Handle a SIGINT interrupt.

Method removeSystemEventTrigger See twisted.internet.interfaces.IReactorCore.removeSystemEventTrigger.
Method callWhenRunning See twisted.internet.interfaces.IReactorCore.callWhenRunning.
Method startRunning Method called when reactor starts: do some initialization and fire startup events.

Method suggestThreadPoolSize See twisted.internet.interfaces.IReactorThreads.suggestThreadPoolSize.
Method callFromThread Cause a function to be executed by the reactor thread.
Method _reallyStartRunning Method called to transition to the running state. This should happen in the during startup event trigger phase.

def _workerInThread(self): (source)
Undocumented
def _doSelectInThread(self, timeout): (source)

Run one iteration of the I/O monitor loop.

This will run all selectables who had input or output readiness waiting for them.

def _interleave(self): (source)
Undocumented
def interleave(self, waker, *args, **kw): (source)

interleave(waker) interleaves this reactor with the current application by moving the blocking parts of the reactor (select() in this case) to a separate thread. This is typically useful for integration with GUI applications which have their own event loop already running.

See the module docstring for more information.
