Interface Schedulable

All Superinterfaces:

Runnable

All Known Implementing Classes:

AsyncEventHandler, BoundAsyncEventHandler, EnergyRealtimeThread, NoHeapRealtimeThread, RealtimeThread

public interface Schedulable
extends Runnable

Handlers and other objects can be run by a Scheduler if they provide a run() method and the methods defined below. The Scheduler uses this information to create a suitable context to execute the run() method.

Method Detail

setReleaseParameters

void setReleaseParameters(ReleaseParameters release)
                          throws IllegalArgumentException,
                                 IllegalStateException

Sets the release parameters associated with this instance of Schedulable. Since this affects the constraints expressed in the release parameters of the existing schedulable objects, this may change the feasibility of the current system. This change becomes effective under conditions determined by the scheduler controlling the schedulable object. For instance, the change may be immediate or it may be delayed until the next release of the schedulable object. The different properties of the release parameters may take effect at different times. See the documentation for the scheduler for details.

Parameters:

release - A ReleaseParameters object which will become the release parameters associated with this after the method call, and take effect as determined by the associated scheduler. If null, the default value is governed by the associated scheduler (a new object is created if the default value is not null). (See PriorityScheduler.)

Throws:

IllegalArgumentException - Never throwed for the moment.

java.lang.IllegalThreadStateException - Never throwed for the moment.

IllegalStateException

setSchedulingParameters

void setSchedulingParameters(SchedulingParameters scheduling)
                             throws IllegalArgumentException,
                                    IllegalAssignmentError

Sets the scheduling parameters associated with this instance of Schedulable. Since this affects the scheduling parameters of the existing schedulable objects, this may change the feasibility of the current system. This change becomes effective under conditions determined by the scheduler controlling the schedulable object. For instance, the change may be immediate or it may be delayed until the next release of the schedulable object. See the documentation for the scheduler for details.

Parameters:

scheduling - A reference to the SchedulingParameters object. If null, the default value is governed by the associated scheduler (a new object is created if the default value is not null). (See PriorityScheduler.)

Throws:

IllegalArgumentException - Never throwed for the moment.

IllegalAssignmentError - Never throwed for the moment.
