class documentation

class MemoryDriver: (source)

In-memory TimeDriver that only moves when advance is called.

Method	`advance`	Advance the clock of `this driver` by `delta` seconds.
Method	`isScheduled`	Does this driver currently have work scheduled with it?
Method	`now`	`TimeDriver.now`
Method	`reschedule`	Schedule the given work to happen at the given time.
Method	`unschedule`	`TimeDriver.unschedule`
Class Variable	`_currentTime`	Undocumented
Instance Variable	`_scheduledWork`	Undocumented

def advance(self, delta: Optional[float] = None) -> float|None: (source) ¶

Advance the clock of this driver by delta seconds.

If no delta is provided, then advance until the next scheduled time when this driver would run something.

Returns
`float\|None`	the amount of time that was advanced, or None if no work was scheduled.

def isScheduled(self) -> bool: (source) ¶

Does this driver currently have work scheduled with it?

def reschedule(self, desiredTime: float, work: Callable[[], None]): (source) ¶

Schedule the given work to happen at the given time.

`TimeDriver.reschedule`
Note
In order to avoid infinite loops where time is not moving forward while work is being scheduled at the current moment or in the past, time (as referenced by `MemoryDriver.now`) will always advance by at least one ULP, so if `desiredTime` is before or exactly `now`, by the time `work` is run, `now` will be very slightly greater.
