          modhelxs.simulation.SynchronizingRTClock

public class SynchronizingRTClock
extends DrivingClock<java.lang.Long>

A driving clock that ticks on real time. If you put a tick on this clock, it will become "now" at the time of its tag.

Method Summary

void	activate() Activate the clock: make it ready to produce a tick and notify the engine.
void	adjustTime(long delta) Adjust the reference time when missing real time dead lines.
ClockBackupInterface<java.lang.Long>	backup()
void	cancel() Cancel the clock: stop waiting for the driving event.
java.lang.Long	getNextTime() Compute the time for the next tick.
long	getRealTime()
Tick<java.lang.Long>	newTick() This clock should have only one tick, so we can't add new ones.
void	removeTick(int i) This clock manages its tick by itself, so we cannot remove them.
void	removeTick(Tick<java.lang.Long> tick) This clock manages its tick by itself, so we cannot remove them.
void	resetClock() Reset the now attribute and the tag of the unique tick of this clock.
void	restore(ClockBackupInterface<java.lang.Long> backup) This clock should have only one tick, so it cannot be restored.
void	wrapup() Release the ressources used by the clock, called at the end of the simulation.

SynchronizingRTClock

public SynchronizingRTClock(java.lang.String name)

Method Detail

getRealTime

public long getRealTime()

getNextTime

public java.lang.Long getNextTime()

Compute the time for the next tick. If this time is is the past, add as many periods as necessary to bring it in the future.

adjustTime

public void adjustTime(long delta)

Adjust the reference time when missing real time dead lines.

activate

public void activate()

Description copied from class: DrivingClock

Activate the clock: make it ready to produce a tick and notify the engine.

Specified by:

activate in class DrivingClock<java.lang.Long>

cancel

public void cancel()

Description copied from class: DrivingClock

Cancel the clock: stop waiting for the driving event.

Specified by:

cancel in class DrivingClock<java.lang.Long>

newTick

public Tick<java.lang.Long> newTick()

This clock should have only one tick, so we can't add new ones.

Overrides:
