Member Function Documentation

void SObservable::addObserver (  SObserver &    obs )  [inline, inherited]

Here another component can register himself as observer of this component Parameters: obs  observer that wants to be notified of events created by this class

void SBrdCastAlgorithm::broadcastMsg (  int    msg )  [inherited]

If another message is being broadcasted, stop it

void SObservable::deleteObserver (  SObserver &    obs )  [inline, inherited]

Here another component can delete himself from the list of observers of this component Parameters: obs  observer that doesn't want to be notified anymore

leda_list< SBroadcastRequ * > SBrdCastAlgorithm::getActiveRequ (    )  [inherited]

Get all active requests. A request is active, if it's released and not completely answered yet.

int SBrdCastAlgorithm::getBroadcastedMsg (    )  [inherited]

Get the message which is currently being broadcasted. Returns: -1 if none

const SClassification & SBrdCastAlgorithm::getClassification (    )  [virtual, inherited]

Returns the classification scheme of the problem, which the algorithm is able to solve. NOTE: will be abstract! Returns: problem classification Implements SSchedAlgorithm.

virtual leda_string SSchedAlgorithm::getCurrentActionDescription (  const int    level )  const [inline, virtual, inherited]

Clones a scheduling algorithm. Returns: pointer to the cloned algorithm

const leda_string SBrdCastSSTF::getDescription (    )  [virtual]

Returns a textual description about this algorithm. This should contain at least the solved problem classification, complexity and a short description how the algorithm works Returns: description Reimplemented from SBrdCastAlgorithm.

SLeaBibEntry & SBrdCastAlgorithm::getLeaBibEntry (    )  [virtual, inherited]

Returns a dictionary providing detailed information about the algorithm NOTE: will be abstract! Returns: dictionary Implements SSchedAlgorithm.

const leda_string & SBrdCastSSTF::getName (    )  [virtual]

Returns the name of the scheduling algorithm, e.g. "Coffman-Graham" NOTE: will be abstract! Returns: algorithms name Reimplemented from SBrdCastAlgorithm.

const leda_string& SSchedAlgorithm::getNameFromClass (    )  [static, inherited]

int SBrdCastAlgorithm::getNumOfMsgs (    )  [inherited]

Get the number of messages.

const STaskSystem& SSchedAlgorithm::getTaskSystem (    )  const [inline, inherited]

Get a read-only reference to the tasksystem. Returns: tasksystem

STaskSystem& SSchedAlgorithm::getTaskSystem (    )  [inline, inherited]

Get a reference to the tasksystem. Returns: tasksystem

double SBrdCastSSTF::innerLoop (  const leda_list< STSysSchedEvent > &    rEvents )  [virtual]

Allocating and deallocating of jobs on machines. The algorithm gets the events of the current simulation step, in order to react on these events ("online algorithm"). The algorithm can define a relative alarm time (relative to the current simumlation step); then the tasksystem will advance until the alarm time and call innerLoop() again. This is used for preemtion for instance. If this time is <= 0 the alarm function is deactivated. Parameters: rEvents  list of scheduling events Returns: relative alarm time Reimplemented from SBrdCastAlgorithm.

bool SSchedAlgorithm::isFinished (    )  [virtual, inherited]

Returns whether the algorithm is finished. The default implementation checks if all jobs are finished. Returns: true, if the algorithm is finished and therefore the simulation shall terminate. Reimplemented in SPlayer, SSmithsRatioRule, and SSmithWSEPT.

void SObservable::notifyObservers (  const SEvent &    event )  [inline, inherited]

Inform all observers of this component about an event. The Observers will receive this event by their SObserver::update()-method. Parameters: event  an event that is sent to all observers of this component See also: SObserver::update()

void SSchedAlgorithm::setCurrentActionDescription (  const int    level, leda_string    descr )  [protected, virtual, inherited]

virtual void SSchedAlgorithm::setTaskSystem (  STaskSystem &    rTS )  [inline, virtual, inherited]

This should contain initialization code which shall be run only the first time the algorithm works on a specific task system. Parameters: rTS  reference to the tasksystem

void SBrdCastAlgorithm::startup (    )  [virtual, inherited]

Called before a simulation run starts. Reimplemented from SSchedAlgorithm. Reimplemented in SBrdCastEQUIEDF, and SBrdCastPushGreedy.

void SBrdCastAlgorithm::stopBroadcast (    )  [inherited]

Stop broadcasting current message, do nothing, if no message is being broadcasted
