twisted.application.runner.

Known subclasses: twisted.application.runner.test.test_runner.DummyRunner

Twisted application runner.

Method	run	Run this command.
Method	killIfRequested	If `self._kill` is true, attempt to kill a running instance of the application.
Method	startLogging	Start the `twisted.logger` logging system.
Method	startReactor	Register `self._whenRunning` with the reactor so that it is called once the reactor is running, then start the reactor.
Method	whenRunning	Call `self._whenRunning` with `self._whenRunningArguments`.
Method	reactorExited	Call `self._reactorExited` with `self._reactorExitedArguments`.
Class Variable	_log	The logger attached to this class. (type: `Logger`)
Instance Variable	_reactor	The reactor to start and run the application in. (type: `IReactorCore`)
Instance Variable	_pidFile	The file to store the running process ID in. (type: callable that takes a single writable file-like object argument and returns a `twisted.logger.FileLogObserver`)
Instance Variable	_kill	Whether this runner should kill an existing running instance of the application. (type: `bool`)
Instance Variable	_defaultLogLevel	The default log level to start the logging system with. (type: `constantly.NamedConstant` from `LogLevel`)
Instance Variable	_logFile	A file stream to write logging output to. (type: writable file-like object)
Instance Variable	_fileLogObserverFactory	A factory for the file log observer to use when starting the logging system.
Instance Variable	_whenRunning	Hook to call after the reactor is running; this is where the application code that relies on the reactor gets called. (type: callable that takes the keyword arguments specified by `whenRunningArguments`)
Instance Variable	_whenRunningArguments	Keyword arguments to pass to `whenRunning` when it is called. (type: `dict`)
Instance Variable	_reactorExited	Hook to call after the reactor exits. (type: callable that takes the keyword arguments specified by `reactorExitedArguments`)
Instance Variable	_reactorExitedArguments	Keyword arguments to pass to `reactorExited` when it is called. (type: `dict`)
