Instance Variable | _stopped | A flag which is true between paired calls to reactor.run and

Instance Variable | _justStopped | A flag which is true between the time reactor.stop is called

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. |

Implementation of read-only IReactorPluggableNameResolver.nameResolver
.
Wake up the event loop.
Do one iteration over the readers and writers which have been added.
Return a Deferred that will resolve a hostname.
See twisted.internet.interfaces.IReactorCore.stop.
See twisted.internet.interfaces.IReactorCore.crash.
Reset reactor state tracking attributes and re-initialize certain
state-transition helpers which were set up in __init__
but
later destroyed (through use).
Handle a SIGINT interrupt.

Handle a SIGBREAK interrupt.

Method called when reactor starts: do some initialization and fire startup events.
Don't call this directly, call reactor.run() instead: it should take care of calling this.
This method is somewhat misnamed. The reactor will not necessarily be in the running state by the time this method returns. The only guarantee is that it will be on its way to the running state.
Method called to transition to the running state. This should happen in the during startup event trigger phase.
See twisted.internet.interfaces.IReactorTime.callLater.
Return all the outstanding delayed calls in the system. They are returned in no particular order. This method is not efficient -- it is really only meant for test cases.
Returns | A list of outstanding delayed calls. |
Determine the longest time the reactor may sleep (waiting on I/O notification, perhaps) before it must wake up to service a time-related event.
Returns | The maximum number of seconds the reactor may sleep. (type: float ) |
Check for valid arguments and environment to spawnProcess.
Returns | A two element tuple giving values to use when creating the process. The
first element of the tuple is a list of bytes
giving the values for argv of the child process. The second element of the
tuple is either None
if env was None
or a dict mapping bytes environment keys to
bytes environment values. |
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 _initThreadPool
.
Cause a function to be executed by the reactor thread.
Use this method when you want to run a function in the reactor's thread
from another thread. Calling callFromThread
should wake up the main thread (where reactor.run()
is executing) and run the given callable in that thread.
If you're writing a multi-threaded application the callable
may need to be thread safe, but this method doesn't require it as such. If
you want to call a function in the next mainloop iteration, but you're in
the same thread, use callLater
with a delay of 0.
