Inherited from _SignalReactorMixin (via PosixReactorBase):
Method | startRunning | Extend the base implementation in order to remember whether signal handlers should be installed later. |
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 PosixReactorBase):
Method | _disconnectSelectable | Utility function for disconnecting a selectable. |

Method | startRunning | Method called when reactor starts: do some initialization and fire startup events. |
Method | getDelayedCalls | No summary |

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. |
Instance Variable | _exitSignal | See _ISupportsExitSignalCapturing._exitSignal |
Method | _reallyStartRunning | Method called to transition to the running state. This should happen in the during startup event trigger phase. |

Wake up the event loop.
Run one iteration of the I/O monitor loop.
This will run all selectables who had input or output readiness waiting for them.
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.
Add a FileDescriptor for notification of data available to read.
Add a FileDescriptor for notification of data available to write.
Remove a Selectable for notification of data available to read.
Remove a Selectable for notification of data available to write.
Remove all readers and writers.
Should not remove reactor internal reactor connections (like a waker).
Returns | A list of IReadDescriptor
and IWriteDescriptor
providers which were removed. |
Return the list of file descriptors currently monitored for input events by the reactor.
Returns | the list of file descriptors monitored for input events. (type: list of IReadDescriptor ) |
Return the list file descriptors currently monitored for output events by the reactor.
Returns | the list of file descriptors monitored for output events. (type: list of IWriteDescriptor ) |
Extend the base stop implementation to also wake up the select thread so
that runUntilCurrent
notices the reactor should stop.
Fire 'startup' System Events, move the reactor to the 'running' state,
then run the main loop until it is stopped with stop()
or
crash()
.
