Constructor Detail

SimQueueQoSStateHandler

public SimQueueQoSStateHandler(boolean comparableQoS)

Creates a new handler.

Creates and maintains the mapping from QoS values onto jobs present with that QoS value. Depending upon the parameter, a HashMap (false) or a TreeMap (true) is used.

Parameters:

comparableQoS - Whether the underlying QoS class to support is Comparable.

getJobsQoSMap()

Method Detail

getHandlerName

public final String getHandlerName()

Returns "SimQueueQoSHandler".

Specified by:

getHandlerName in interface SimQueueStateHandler

Returns:

"SimQueueQoSHandler".

initHandler

public final void initHandler(DefaultSimQueueState queueState)

Description copied from interface: SimQueueStateHandler

Initializes the handler, and passes the DefaultSimQueueState object.

This method is called only once during registration at the DefaultSimQueueState object.

Specified by:

initHandler in interface SimQueueStateHandler

Parameters:

queueState - The DefaultSimQueueState at which we register, non-null.

See Also:

DefaultSimQueueState.registerHandler(org.javades.jqueues.r5.util.predictor.state.SimQueueStateHandler)

resetHandler

public void resetHandler(DefaultSimQueueState queueState)

Description copied from interface: SimQueueStateHandler

Resets the (state represented by) this handler.

Specified by:

resetHandler in interface SimQueueStateHandler

Parameters:

queueState - The DefaultSimQueueState at which we are registered, non-null.

See Also:

SimQueueState.reset(), DefaultSimQueueState.reset()

getJobsQoSMap

public final Map<P,Set<J>> getJobsQoSMap()

Maps QoS values onto jobs present with that QoS value.

Mapping is 1 to many. Empty and null sets are not allowed. A job can be present in at most one of the value sets.

See the constructor of this handler for details about finer structuring of the map (e.g., when caller may assume it is a NavigableMap.

Returns:

A mapping of QoS values onto jobs present with that QoS value.

updateJobsQoSMap

public void updateJobsQoSMap()
