twisted.internet.task.Clock

class documentation

class Clock: (source)

Known subclasses: twisted.internet.testing.MemoryReactorClock

Implements interfaces: twisted.internet.interfaces.IReactorTime

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.

Method	`__init__`	Undocumented
Method	`advance`	Move time on this clock forward by the given amount and run whatever pending calls should be run.
Method	`callLater`	See `twisted.internet.interfaces.IReactorTime.callLater`.
Method	`getDelayedCalls`	See `twisted.internet.interfaces.IReactorTime.getDelayedCalls`
Method	`pump`	Advance incrementally by the given set of times.
Method	`seconds`	Pretend to be time.time(). This is used internally when an operation such as `IDelayedCall.reset` needs to determine a time value relative to the current time.
Class Variable	`rightNow`	Undocumented
Instance Variable	`calls`	Undocumented
Method	`_sortCalls`	Sort the pending calls according to the time they are scheduled.

def __init__(self): (source)

overridden in twisted.internet.testing.MemoryReactorClock

Undocumented

def advance(self, amount): (source)

Move time on this clock forward by the given amount and run whatever pending calls should be run.

Parameters
amount:`float`	The number of seconds which to advance this clock's time.

def callLater(self, delay, callable, *args, **kw): (source)

from twisted.internet.interfaces.IReactorTime

See twisted.internet.interfaces.IReactorTime.callLater.

Parameters
delay	Undocumented
callable:`Callable[..., Any]`	Undocumented
*args	Undocumented
**kw	Undocumented

def getDelayedCalls(self): (source)

from twisted.internet.interfaces.IReactorTime

See twisted.internet.interfaces.IReactorTime.getDelayedCalls

def pump(self, timings): (source)

Advance incrementally by the given set of times.

Parameters
timings:iterable of `float`	Undocumented

def seconds(self): (source)

from twisted.internet.interfaces.IReactorTime

Pretend to be time.time(). This is used internally when an operation such as IDelayedCall.reset needs to determine a time value relative to the current time.

Returns
`float`	The time which should be considered the current time.

rightNow: float = (source)

Undocumented

calls: list = (source)

Undocumented

def _sortCalls(self): (source)

Sort the pending calls according to the time they are scheduled.
