Class SolarToggle

java.lang.Object
  stella.util.SolarToggle

All Implemented Interfaces:

Toggling

public class SolarToggle
extends Object
implements Toggling

A Solar height toggle with two different values. If the sun is setting, i.e. the last measurement was higher than the current, then the set value is used for Toggling action, on sun rise, the rise value is used. The action is similar to a SchmidtTrigger, but the latter does not allow a setting value higher than a rising value.

Field Summary

private double	lastsol The last measurement added.
private double	rise The solar height toggle at sun rise.
private double	set The solar height toggle at sun set.

Constructor Summary

protected	SolarToggle() Common constructor.
	SolarToggle(double offtrig, double ontrig) Constructs a new Schmidt trigger.
	SolarToggle(String parameter) Constructs a new Schmidt trigger.

Method Summary

boolean	addHit(double val) Return true, if the argument value is above the appropriate trigger.
protected void	setTriggers(double offtrig, double ontrig) Sets the two trigger values.
String	toString() Returns the two toggle edges as a description.

Field Detail

lastsol

private double lastsol

The last measurement added.

set

private double set

The solar height toggle at sun set.

rise

private double rise

The solar height toggle at sun rise.

Constructor Detail

SolarToggle

protected SolarToggle()

Common constructor. Do not use. The toggle value starts with false;

SolarToggle

public SolarToggle(String parameter)

Constructs a new Schmidt trigger. The two toggle values, #off and #on must be separated with a comma.

SolarToggle

public SolarToggle(double offtrig,
                   double ontrig)

Constructs a new Schmidt trigger. Note that the first argument, the #off trigger must be less than the second argument, the #on trigger.

Method Detail

setTriggers

protected void setTriggers(double offtrig,
                           double ontrig)

Sets the two trigger values. The first argument is the sun-set value, the second the sun rise.

addHit

public boolean addHit(double val)

Return true, if the argument value is above the appropriate trigger. If the lastsol state of the Schmidt trigger is on, than the #on value is used, the #off value otherwise.

addHit in interface Toggling

toString

public String toString()

Returns the two toggle edges as a description.

Overrides:
