Python in a Nutshell

scheduler

Synopsis

class scheduler(timefunc,delayfunc)

An instance s of scheduler is initialized with two functions, which s then uses for all time-related operations. timefunc must be callable without arguments to get the current time instant (in any unit of measure), meaning that you can pass time.time. delayfunc must be callable with one argument (a time duration, in the same units timefunc returns), and it should delay for about that amount of time, meaning you can pass time.sleep. scheduler also calls delayfunc with argument 0 after each event, to give other threads a chance; again, this is compatible with the behavior of time.sleep.

A scheduler instance s supplies the following methods.
