Known subclasses: twisted.internet.glib2reactor.Glib2Reactor, twisted.manhole.gladereactor.GladeReactor

PyGTK+ 2 event loop reactor.

Method

__init__

Undocumented

Inherited from GlibReactorBase:

Method	input_add	Undocumented
Method	addReader	Add a FileDescriptor for monitoring of data available to read.
Method	addWriter	Add a FileDescriptor for monitoring ability to write data.
Method	getReaders	Retrieve the list of current FileDescriptor monitored for reading.
Method	getWriters	Retrieve the list of current FileDescriptor monitored for writing.
Method	removeAll	Remove monitoring for all registered FileDescriptors.
Method	removeReader	Stop monitoring the given FileDescriptor for reading.
Method	removeWriter	Stop monitoring the given FileDescriptor for writing.
Method	iterate	One iteration of the event loop, for trial's use.
Method	crash	Crash the reactor.
Method	stop	Stop the reactor.
Method	run	Run the reactor.
Method	callLater	Schedule a DelayedCall.
Instance Variable	_sources	A dictionary mapping FileDescriptor instances to GSource handles.
Instance Variable	_reads	A set of FileDescriptor instances currently monitored for reading.
Instance Variable	_writes	A set of FileDescriptor instances currently monitored for writing.
Instance Variable	_simtag	A GSource handle for the next simulate call.
Method	_handleSignals	Extend the basic signal handling logic to also support handling SIGCHLD to know when to try to reap child processes.
Method	_ioEventCallback	Called by event loop when an I/O event occurs.
Method	_add	No summary
Method	_remove	Remove monitoring the given FileDescriptor for either reading or writing. If it's still monitored for the other operation, we re-register the FileDescriptor for only that operation.
Method	_reschedule	Schedule a glib timeout for _simulate.
Method	_simulate	Run timers, and then reschedule glib timeout for next scheduled event.

Inherited from PosixReactorBase (via GlibReactorBase):

Method	installWaker	Install a `waker' to allow threads and signals to wake up the IO thread.
Method	spawnProcess	Spawn a process, with a process protocol.
Method	listenUDP	Connects a given DatagramProtocol to the given numeric UDP port.
Method	listenMulticast	Connects a given DatagramProtocol to the given numeric UDP port.
Method	connectUNIX
Method	listenUNIX
Method	listenUNIXDatagram	Connects a given DatagramProtocol to the given path.
Method	connectUNIXDatagram	Connects a ConnectedDatagramProtocol instance to a path.
Method	adoptStreamPort	Create a new IListeningPort from an already-initialized socket.
Method	listenTCP
Method	connectTCP
Method	connectSSL
Method	listenSSL
Method	listenWith	Undocumented
Method	connectWith	Undocumented
Instance Variable	_childWaker	None or a reference to the _SIGCHLDWaker which is used to properly notice child process termination.
Method	_uninstallHandler	If a child waker was created and installed, uninstall it now.
Method	_removeAll	Remove all readers and writers, and list of removed IReadDescriptors and IWriteDescriptors.

Inherited from _SignalReactorMixin (via GlibReactorBase, PosixReactorBase):

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

Inherited from _DisconnectSelectableMixin (via GlibReactorBase, PosixReactorBase):

Method

_disconnectSelectable

Utility function for disconnecting a selectable.

Inherited from ReactorBase (via GlibReactorBase, PosixReactorBase):

Instance Variable	running	See IReactorCore.running
Method	installResolver	Set the internal resolver to use to for name lookups.
Method	wakeUp	Wake up the event loop.
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	sigInt	Handle a SIGINT interrupt.
Method	sigBreak	Handle a SIGBREAK interrupt.
Method	sigTerm	Handle a SIGTERM interrupt.
Method	disconnectAll	Disconnect every reader, and writer in the system.
Method	fireSystemEvent	See twisted.internet.interfaces.IReactorCore.fireSystemEvent.
Method	addSystemEventTrigger	See twisted.internet.interfaces.IReactorCore.addSystemEventTrigger.
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	getDelayedCalls	No summary
Method	timeout	Undocumented
Method	runUntilCurrent	Run all pending timed calls.
Method	callFromThread 0	See twisted.internet.interfaces.IReactorThreads.callFromThread.
Method	getThreadPool	See twisted.internet.interfaces.IReactorThreads.getThreadPool.
Method	callInThread	See twisted.internet.interfaces.IReactorThreads.callInThread.
Method	suggestThreadPoolSize	See twisted.internet.interfaces.IReactorThreads.suggestThreadPoolSize.
Method	callFromThread	Cause a function to be executed by the reactor thread.
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. (type: bool)
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. This should be replaced with an explicit state machine. (type: bool)
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. (type: bool)
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.
Method	_reallyStartRunning	Method called to transition to the running state. This should happen in the during startup event trigger phase.
Method	_moveCallLaterSooner	Undocumented
Method	_cancelCallLater	Undocumented

Method	_stopThreadPool	No summary

Inherited from _PollLikeMixin (via GlibReactorBase):
