Detailed Description

Representation of a precedence relation as directed, acyclic graph (DAG), its classifier if "Dag". The nodes of the DAG are the jobs in the tasksystem, the edges are dependencies between jobs: job A must be finished, before job B can be scheduled. Access the modifier to set properties.

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

virtual void STypeInfo::assureInstanceOf (  const leda_string &    classifier )  const [pure virtual, inherited]

The same as isInstanceOf(), only that the program is stopped with an error in case of failure Parameters: classifier  e.g. "P", "Q", "R", etc

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

virtual leda_string STypeInfo::getClassifier (    )  [pure virtual, inherited]

Get the classifier of the object, using the classification scheme. E.g. "P" for Identical Processors Returns: classifier string

virtual const leda_graph& SPrecDAG::getGraph (    )  const [inline, virtual]

Get read-only access to the graph Implements SPrecDAGInt.

SJob& SPrecDAG::getJob (  leda_node    v )  const [inline, virtual]

Get job in tasksystem that corresponds to node in DAG Parameters: v  node in DAG Returns: job in tasksystem Implements SPrecDAGInt.

virtual SPrecRelationMod& SPrecDAG::getModifier (    )  [inline, virtual]

Get access to the modifier Implements SPrecRelation.

leda_node SPrecDAG::getNode (  const SJob &    job )  const [inline, virtual]

Get node in DAG that corresponds to job in tasksystem Parameters: job  job in tasksystem Returns: node in DAG Implements SPrecDAGInt.

const STaskSystem& SPrecDAG::getTaskSystem (    )  const [inline]

Get reference to tasksystem

virtual SVisPrecDAG& SPrecDAG::getVisPrecDAG (    )  [inline, virtual]

Visualization only: Get access to node positions and edge bends Implements SPrecDAGInt.

bool SPrecDAG::isAvailable (  const SJob &    job )  const [virtual]

Return whether scheduling the job would violate the precedence relation. Parameters: job  job Returns: true, if no violation of precedence realation, otherwise false Implements SPrecRelation.

virtual bool STypeInfo::isInstanceOf (  const leda_string &    classifier )  const [pure virtual, inherited]

Checks whether the object is an instance of the specified or a specialized class Parameters: classifier  e.g. "P", "Q", "R", etc Returns: true if the object can be casted to the specified class

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()
