Scheduling utility methods and classes.

Author Jp Calderone

Class	LoopingCall	Call a function repeatedly.
Class	SchedulerError	No summary
Class	SchedulerStopped	The operation could not complete because the scheduler was stopped in progress or was already stopped.
Class	TaskFinished	The operation could not complete because the task was already completed, stopped, encountered an error or otherwise permanently stopped running.
Class	TaskDone	The operation could not complete because the task was already completed.
Class	TaskStopped	The operation could not complete because the task was stopped.
Class	TaskFailed	The operation could not complete because the task died with an unhandled error.
Class	NotPaused	This exception is raised when a task is resumed which was not previously paused.
Class	CooperativeTask	A `CooperativeTask` is a task object inside a `Cooperator`, which can be paused, resumed, and stopped. It can also have its completion (or termination) monitored.
Class	Cooperator	Cooperative task scheduler.
Function	coiterate	Cooperatively iterate over the given iterator, dividing runtime between it and all other iterators which have been passed to this function and not yet exhausted.
Function	cooperate	Start running the given iterator as a long-running cooperative task, by calling next() on it as a periodic timed event.
Class	Clock	Provide a deterministic, easily-controlled implementation of `IReactorTime.callLater`. This is commonly useful for writing deterministic unit tests for code which schedules events using this API.
Function	deferLater	Call the given function after a certain period of time has passed.
Class	_Timer	Undocumented
Function	_defaultScheduler	Undocumented

def _defaultScheduler(x): (source)

Undocumented

def coiterate(iterator): (source)

Cooperatively iterate over the given iterator, dividing runtime between it and all other iterators which have been passed to this function and not yet exhausted.

Parameters	iterator	the iterator to invoke.
Returns	a Deferred that will fire when the iterator finishes.

def cooperate(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 deferLater(clock, delay, callable, *args, **kw): (source)

Call the given function after a certain period of time has passed.

Parameters	clock	The object which will be used to schedule the delayed call. (type: `IReactorTime` provider)
	delay	The number of seconds to wait before calling the function. (type: `float` or `int`)
	callable	The object to call after the delay.
	*args	The positional arguments to pass to `callable`.
	**kw	The keyword arguments to pass to `callable`.
Returns	A deferred that fires with the result of the callable when the specified time has elapsed. (type: `defer.Deferred`)
