Method Summary

Modifier and Type	Method	Description
void	idledown()	block the thread till a moment at which all scheduled tasks have completed and then shutdown the scheduler does not prevent scheduling new tasks (from other threads) until the shutdown is complete so such a task could be partially executed
boolean	isEmpty()
boolean	isEmptyish()	are the queues empty allows false positives, but not false negatives ie, if this method returns false, then at some moment during the call at least one queue was non-empty if it returns true then for each queue there was a moment during the call when it was empty
boolean	isPinnable()
static void	main(String[] args)	run the main method from another class using this scheduler as the default scheduler
