Method Summary

Modifier and Type	Method and 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	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

AffineScheduler

protected AffineScheduler()

AffineScheduler

public AffineScheduler(int numThreads,
                       int queueSize)

create the scheduler

Parameters:

numThreads - the number of threads to use, or use the default if less than one

queueSize - the queue size to use, or use the default if less than one

Method Detail

schedule

public void schedule(int index,
                     Task t)

Description copied from class: Scheduler

schedule a task to run

Specified by:

schedule in class Scheduler

Parameters:

index - the index of the executor to use, or less than zero to use the default (round robin) assignment

t - the task

idledown

public void idledown()

Description copied from class: Scheduler

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

Specified by:

idledown in class Scheduler

next

protected int next()

scheduleTimer

public void scheduleTimer(Timer t)

Specified by:

isEmptyish

public boolean isEmptyish()

Description copied from class: Scheduler

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

Specified by:

isEmptyish in class Scheduler
