Method | run | Undocumented |
Method | mainLoop | Undocumented |

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. |
Inherited from ReactorBase (via PosixReactorBase):
Instance Variable | running | See IReactorCore.running |

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 | stop | See twisted.internet.interfaces.IReactorCore.stop. |

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. |

FileDescriptor
which have been registered with the reactor.
All FileDescriptors
which are currently receiving read or
write readiness notifications will be present as values in this dictionary.
_poller
for read readiness notifications which will be
dispatched to the corresponding FileDescriptor
instances in
_selectables
.
_poller
for write readiness notifications which will be
dispatched to the corresponding FileDescriptor
instances in
_selectables
.
_ContinuousPolling
instance, used to handle file descriptors (e.g. filesytem files) that are
not supported by epoll(7)
.
It takes care of adding it if new or modifying it if already added for another state (read -> read/write for example).
It does the inverse job of _add, and also add a check in case of the fd has gone away.
Returns | the list of file descriptors monitored for input events. (type: list of IReadDescriptor ) |
Returns | the list of file descriptors monitored for output events. (type: list of IWriteDescriptor ) |
