Interface Schedulable

All Superinterfaces:

java.lang.Runnable

All Known Implementing Classes:

AsyncEventHandler, RealtimeThread

public interface Schedulable

extends java.lang.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

addToFeasibility

public boolean addToFeasibility()

Inform the scheduler and cooperating facilities that the resource demands (as expressed in the associated instances of SchedulingParameters, ReleaseParameters, MemoryParameters, and ProcessingGroupParameters) of this instance of Schedulable will be considered in the feasibility analysis of the associated Scheduler until further notice. Whether the resulting system is feasible or not, the addition is completed.

Returns:

true if the resulting system is feasible.

getMemoryParameters

public MemoryParameters getMemoryParameters()

Returns:

the MemoryParameters of this schedulable object.

getProcessingGroupParameters

public ProcessingGroupParameters getProcessingGroupParameters()

Returns:

the ProcessingGroupParameters of this schedulable object.

getReleaseParameters

public ReleaseParameters getReleaseParameters()

Returns:

the ReleaseParameters of this schedulable object.

getScheduler

public Scheduler getScheduler()

Returns:

the Scheduler of this schedulable object.

getSchedulingParameters

public SchedulingParameters getSchedulingParameters()

Returns:

the SchedulingParameters of this schedulable object.

removeFromFeasibility

public boolean removeFromFeasibility()

Inform the scheduler and cooperating facilities that the resource demands, as expressed in the associated instances of SchedulingParameters, ReleaseParameters, MemoryParameters, and ProcessingGroupParameters, of this instance of Schedulable should no longer be considered in the feasibility analysis of the associated Scheduler. Whether the resulting system is feasible or not, the subtraction is completed.

Returns:

true if the resulting system is feasible.
