Member Function Documentation

addThread()

void RoundRobin::addThread ( Thread *  pThread )

virtual

Adds a new thread to be scheduled.

Implements SchedulingAlgorithm.

Definition at line 50 of file RoundRobin.cc.

enqueue()

void RoundRobin::enqueue ( Thread *  pThread )

private

Definition at line 57 of file RoundRobin.cc.

getNext()

Thread * RoundRobin::getNext ( Thread *  pCurrentThread )

virtual

Return the next thread that should be scheduled for the given Processor.

Parameters

pProcessor

The Processor for which the scheduling should take place - this is provided for heuristic purposes (core affinity etc).

Note

It is assumed that this function will set the Thread's TTL and other such values itself.

Implements SchedulingAlgorithm.

Definition at line 110 of file RoundRobin.cc.

hasReady()

bool RoundRobin::hasReady ( )

virtual

Whether the ready queue contains a runnable peer.

Implements SchedulingAlgorithm.

Definition at line 150 of file RoundRobin.cc.

isReady()

bool RoundRobin::isReady ( Thread *  pThread )

staticprivate

Definition at line 176 of file RoundRobin.cc.

removeThread()

void RoundRobin::removeThread ( Thread *  pThread )

virtual

Removes a thread - this thread should no longer be scheduled.

Implements SchedulingAlgorithm.

Definition at line 52 of file RoundRobin.cc.

threadStatusChanged()

void RoundRobin::threadStatusChanged ( Thread *  pThread )

virtual

Notifies us that the status of a thread has changed, and that we may need to take action.

Implements SchedulingAlgorithm.

unlink()

void RoundRobin::unlink ( Thread *  pThread )

private

Definition at line 80 of file RoundRobin.cc.
