public class InferPark
extends AbstractTrigger
implements ParameterDepending, Reloadable

Tries to infer the parking state of the telescope by checking the telescope's power state and altitude. Park is assumed if the power is off and the telescope is close to the upright position.

Constructor Summary

InferPark(Map prop)
Constructs a new park-telescope inferrer trigger.

Method Summary

Date	getLastToggleTime() Returns a very crude estimate by returning the toggle time of the power trigger.
Boolean	getTrigger() Returns true if power is off and telescope is upright.
void	registerParameter(Parameter what) Registers the telescope height and the telescope power state.
double	rescanned(String key, String old, String newval) As any parameter depending instance we fail if the parameter we depend on is now a different one.
Boolean	setTrigger(Boolean to) Setting the trigger is not allowed.

Method Detail

rescanned

public double rescanned(String key,
                        String old,
                        String newval)

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class AbstractParameter

registerParameter

public void registerParameter(Parameter what)

Registers the telescope height and the telescope power state.

Specified by:
