Concrete methods
Repeated invocations of step with a time bound. The function is repeatedly invoked on the "state" part of its previous output until it returns None or the timeout has been reached. The "value" part of the pair is collected into a sequence.
Repeated invocations of step with a time bound. The function is repeatedly invoked on the "state" part of its previous output until it returns None or the timeout has been reached. The "value" part of the pair is collected into a sequence.
Value parameters

Adds sleep time so code takes up specified duration.
Adds sleep time so code takes up specified duration.
This method does not throw InterruptedException. If the thread is interrupted, the sleeping stops and the thread is left interrupted.
If the code fails, the exception is thrown after the specified delay.
An argument can be used to specify the starting clock, as per getTime; this is useful when a preliminary computation needs to be performed before sleeping. The value of this argument is assumed to be in the past. (In particular, delaying by a negative amount of time does not delay, independently from the start value.)
Value parameters
- start
-

Pauses the calling thread for the specified amount of time.
Pauses the calling thread for the specified amount of time.
This method differs from Thread.sleep is several ways:
- durations are specified in seconds as a floating point number.
- the method never undershoots, as it sometimes happens with
Thread.sleepon some platforms. InterruptedExceptionis not thrown; the thread is left interrupted instead.
