Detailed Description

STaskSystem is the central component where jobs, machines, precedence relation and the algorithm are combined to form a "tasksystem". Access the modifier to add or delete jobs. For changing machines or the precedence relation access the modifier of these components.

Constructor & Destructor Documentation

STaskSystem::STaskSystem (    )

Constructor

STaskSystem::~STaskSystem (    )  [virtual]

Destructor. The task system owns its component and destroys them as well.

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 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

bool STaskSystem::doSimStep (    )

Advance simulation time until the next event happens, change the state of the system and call the inner loop of the algorithm

const SSchedAlgorithm& STaskSystem::getAlgorithm (    )  const [inline]

Get scheduling algorithm.

SJobArray& STaskSystem::getAllJobs (    )  [inline]

Get access to all jobs Returns: array of all jobs

const SJobArray& STaskSystem::getAllJobs (    )  const [inline]

Get read-only access to all jobs Returns: array of all jobs

leda_set< SJob * > STaskSystem::getAvailableJobs (    )

Get available jobs (jobs that can be scheduled according to the precedence relation

const SClassification& STaskSystem::getClassification (    )  const [inline]

Get the classification according to the classification scheme.

leda_set<SJob*> STaskSystem::getFinishedJobs (    )  const [inline]

Get all jobs that are in state FINISHED

leda_set<SJob*> STaskSystem::getHiddenJobs (    )  const [inline]

Get all jobs that are in state HIDDEN

const SJob& STaskSystem::getJob (  int    idx )  const [inline]

Get read-only access to a job with a certain index Precondition: 0 < idx < numJobs() Parameters: idx  index of a job Returns: reference to job with index 'idx'

SJob& STaskSystem::getJob (  int    idx )  [inline]

Get access to a job with a certain index. Precondition: 0 < idx < numJobs() Parameters: idx  index of a job Returns: reference to job with index 'idx'

SMachines& STaskSystem::getMachines (    )  [inline]

Get access to the machines

const SMachines& STaskSystem::getMachines (    )  const [inline]

Get read-only access to the machines

virtual STaskSystemMod& STaskSystem::getModifier (    )  [inline, virtual]

Get access to the tasksystem modifier

leda_array<SPassiveMachines*>& STaskSystem::getPassiveMachines (    )  [inline]

Get access to the passive machines

const leda_array<SPassiveMachines*>& STaskSystem::getPassiveMachines (    )  const [inline]

Get read-only access to the passive machines

SPrecBroker& STaskSystem::getPrecBroker (    )  [inline]

Get access to the precedence relation

SPrecRelation& STaskSystem::getPrecRelation (    )  [inline]

Get access to the master-precedence-relation

const SPrecRelation& STaskSystem::getPrecRelation (    )  const [inline]

Get read-only access to the master-precedence-relation

bool STaskSystem::getRandProcTimes (    )

returns if jobs' processing times are random(1) or known in advance(0)

leda_set< SJob * > STaskSystem::getReadyJobs (    )

Get ready jobs (jobs that are released and available)

leda_set<SJob*> STaskSystem::getRejectedJobs (    )  const [inline]

Get all jobs that are in state REJECTED

leda_set<SJob*> STaskSystem::getReleasedJobs (    )  const [inline]

Get all jobs that are in state RELEASED

SProbabilityDist * STaskSystem::getRelTimeDist (    )

returns the distribution of the jobs' release times

leda_set<SJob*> STaskSystem::getRunningJobs (    )  const [inline]

Get all jobs that are in state RUNNING

double STaskSystem::getTime (    )  const [inline]

Return current simulation time. If simulation is being advanced, e.g. during a call to simulateUntil() then getTime() still returns the simulation time of the last simulation step)

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()

int STaskSystem::numJobs (    )  const [inline]

Return the number of jobs

void STaskSystem::reset (    )

Reset all jobs, machines and startup the algorithm.

void STaskSystem::run (    )  [inline]

Reset and run the algorithm completely

void STaskSystem::setAlgorithm (  SSchedAlgorithm &    alg )

Set scheduling algorithm.

void STaskSystem::setClassification (  const SClassification &    classif )

void STaskSystem::setRelTimeDist (  SProbabilityDist *    dist )

sets distribution for release times of the jobs

void STaskSystem::update (  const SEvent &    event )  [virtual]

Here the tasksystem receives events of observed components Parameters: event  event from observed component Implements SObserver.
