twisted.internet.base._SignalReactorMixin

class documentation

class _SignalReactorMixin: (source)

Known subclasses: twisted.internet.iocpreactor.reactor.IOCPReactor, twisted.internet.posixbase.PosixReactorBase

View In Hierarchy

Private mixin to manage signals: it installs signal handlers at start time, and define run method.

It can only be used mixed in with ReactorBase, and has to be defined first in the inheritance (so that method resolution order finds startRunning first).

Method mainLoop Undocumented
Method run Undocumented
Method startRunning Extend the base implementation in order to remember whether signal handlers should be installed later.
Method _handleSignals Install the signal handlers for the Twisted event loop.
Method _reallyStartRunning Extend the base implementation by also installing signal handlers, if self._installSignalHandlers is true.
Instance Variable _installSignalHandlers A flag which indicates whether any signal handlers will be installed during startup. This includes handlers for SIGCHLD to monitor child processes, and SIGINT, SIGTERM, and SIGBREAK to stop the reactor.

def run(self, installSignalHandlers=True): (source)

Parameters
installSignalHandlers:boolUndocumented
def startRunning(self, installSignalHandlers=True): (source)

Extend the base implementation in order to remember whether signal handlers should be installed later.

Parameters
installSignalHandlers:boolA flag which, if set, indicates that handlers for a number of (implementation-defined) signals should be installed during startup.
def _handleSignals(self): (source)
overridden in twisted.internet.posixbase.PosixReactorBase

Install the signal handlers for the Twisted event loop.

def _reallyStartRunning(self): (source)

Extend the base implementation by also installing signal handlers, if self._installSignalHandlers is true.

_installSignalHandlers = (source)

A flag which indicates whether any signal handlers will be installed during startup. This includes handlers for SIGCHLD to monitor child processes, and SIGINT, SIGTERM, and SIGBREAK to stop the reactor.
