twisted.internet.task.Cooperator : API documentation

Method	__init__	Create a scheduler-like object to which iterators may be added.
Method	coiterate	Add an iterator to the list of iterators this `Cooperator` is currently running.
Method	cooperate	Start running the given iterator as a long-running cooperative task, by calling next() on it as a periodic timed event.
Method	start	Begin scheduling steps.
Method	stop	Stop scheduling steps. Errback the completion Deferreds of all iterators which have been added and forget about them.
Method	_addTask	Add a `CooperativeTask` object to this `Cooperator`.
Method	_removeTask	Remove a `CooperativeTask` from this `Cooperator`.
Method	_tasksWhileNotStopped	Yield all `CooperativeTask` objects in a loop as long as this `Cooperator`'s termination condition has not been met.
Method	_tick	Run one scheduler tick.
Method	_reschedule	Undocumented

def __init__(self, terminationPredicateFactory=_Timer, scheduler=_defaultScheduler, started=True): (source)

Create a scheduler-like object to which iterators may be added.

Parameters	terminationPredicateFactory	A no-argument callable which will be invoked at the beginning of each step and should return a no-argument callable which will return True when the step should be terminated. The default factory is time-based and allows iterators to run for 1/100th of a second at a time.
	scheduler	A one-argument callable which takes a no-argument callable and should invoke it at some future point. This will be used to schedule each step of this Cooperator.
	started	A boolean which indicates whether iterators should be stepped as soon as they are added, or if they will be queued up until `Cooperator.start` is called.

def coiterate(self, iterator, doneDeferred=None): (source)

Add an iterator to the list of iterators this Cooperator is currently running.

Parameters	doneDeferred	If specified, this will be the Deferred used as the completion deferred. It is suggested that you use the default, which creates a new Deferred for you.
Returns	a Deferred that will fire when the iterator finishes.

def cooperate(self, iterator): (source)

Start running the given iterator as a long-running cooperative task, by calling next() on it as a periodic timed event.

Parameters	iterator	the iterator to invoke.
Returns	a `CooperativeTask` object representing this task.

def _tasksWhileNotStopped(self): (source)

Yield all CooperativeTask objects in a loop as long as this Cooperator's termination condition has not been met.
