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.

The last measurement added.

set

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.

toString
