javax.realtime.SchedulingParameters

All Implemented Interfaces:

Serializable, Cloneable, Subsumable<SchedulingParameters>

Direct Known Subclasses:

PriorityParameters

public class SchedulingParameters
extends Object
implements Serializable, Cloneable, Subsumable<SchedulingParameters>

Jamaica Real-Time Specification for Java class SchedulingParameters.

Subclasses of this class provide parameters for schedulable objects used by the scheduler to perform the scheduling of these objects.

NOTE: the methods in this class are not synchronized. They cannot be used by several threads simultaneously without proper explicit synchronization.

Constructor Detail

SchedulingParameters

protected SchedulingParameters()

Constructor to create SchedulingParameters that are not associated with any schedulable object.

SchedulingParameters

protected SchedulingParameters(Affinity affinity)

Creates a new instance of SchedulingParameters.

Parameters:

affinity - Sets the affinity for these parameters. A null value defaults to the affinity of the caller.

Since:

RTSJ 2.0

Method Detail

clone

public Object clone()

clone creates a clone of this object with the same parameters but without association to any schedulable object

Overrides:

clone in class Object

Returns:

a new instance of SchedulableParameters without any associated schedulable objects.

Since:

RTSJ V1.0.1

Cloneable

getAffinity

public Affinity getAffinity()

Determine the affinity set instance associated of these parameters.

Returns:

The associated affinity.

Since:

RTSJ 2.0

subsumes

public boolean subsumes(SchedulingParameters other)

Description copied from interface: Subsumable

Indicates that some set represented by other is subsumed by the set represented by this object.

Specified by:

subsumes in interface Subsumable<SchedulingParameters>

Parameters:

other - The object to be compared with.

Returns:

true when and only when the set represented by other is subsumed by the set represented by this object.

isCompatible

public boolean isCompatible(Scheduler scheduler)

Determines whether this scheduling parameters can be used by tasks scheduled by scheduler.

Parameters:

scheduler - The scheduler to check against

Returns:

true when and only when this can be used with scheduler as the scheduler.

Since:

RTSJ 2.0
