Method _addInternalReader Add a read descriptor which is part of the implementation of the reactor itself.
Method _cancelCallLater Undocumented
Method _initThreadPool Create the threadpool accessible with callFromThread.
Method _initThreads Undocumented
Method _insertNewDelayedCalls Undocumented
Method _makeSignalHandling Get an appropriate signal handling object.
Method _moveCallLaterSooner Undocumented
Method _reallyStartRunning Method called to transition to the running state. This should happen in the during startup event trigger phase.
Method _removeInternalReader Remove a read descriptor which is part of the implementation of the reactor itself.
Method _signalsFactory Get a signal handling object that implements the basic behavior of stopping the reactor on SIGINT, SIGBREAK, and SIGTERM.
Method _stopThreadPool Stop the reactor threadpool. This method is only valid if there is currently a threadpool (created by _initThreadPool). It is not intended to be called directly; instead, it will be called by a shutdown trigger created in ...
Method _uninstallHandler Undocumented
Class Variable _lock Undocumented
Instance Variable _cancellations Undocumented
Instance Variable _eventTriggers Undocumented
Instance Variable _exitSignal See _ISupportsExitSignalCapturing._exitSignal
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
Instance Variable _internalReaders Undocumented
Instance Variable _justStopped A flag which is true between the time reactor.stop is called and the time the shutdown system event is fired. This is used to determine whether that event should be fired after each iteration through the mainloop...
Instance Variable _newTimedCalls Undocumented
Instance Variable _pendingTimedCalls Undocumented
Instance Variable _registerAsIOThread A flag controlling whether the reactor will register the thread it is running in as the I/O thread when it starts. If True, registration will be done, otherwise it will not be.
Instance Variable _signals An object which knows how to install and uninstall the reactor's signal-handling behavior.
Instance Variable _started A flag which is true from the time reactor.run is called until the time reactor.run returns. This is used to prevent calls to reactor.run on a running reactor. This should be replaced with an explicit state machine.
Instance Variable _startedBefore Undocumented
Instance Variable _stopped A flag which is true between paired calls to reactor.run and reactor.stop. This should be replaced with an explicit state machine.
