Class Clock

Base class for the resource manager's clock.

The clock is in charge of periodically waking the resource manager so it will process new requests and handle existing reservations. This is a base class defining abstract methods.

get_next_schedulable_time(self)

source code

Return the next time at which resources could be scheduled.

The "next schedulable time" server sanity measure when running in real time (to avoid scheduling something "now" to actually have "now" be in the past once the scheduling function returns. i.e., the "next schedulable time" has nothing to do with whether there are resources available at that time or not.

run(self)

source code

Start and run the clock. This function is, in effect, the main loop of the resource manager.

stop(self)

source code

Stop the clock.

Stopping the clock makes Haizea exit.
