public class FractionalExposureTime
extends AbstractValue
implements ParameterDepending, Reloadable

This parameter gives the fractional remaining exposure time. It uses a ExposureTimeLeft parameter and queries its current value plus its count down value. The fractional exposure time is then the total time minus the current count down divided by the total time and thus between zero and one.

Field Detail

KEY_EXPOSURETIME

public static final String KEY_EXPOSURETIME

The name of the exposure time left count down.

Constant Field Values

DEFNAME

public static final String DEFNAME

The name of this global (jd).

Constant Field Values

DEFEXPOSURETIME

private static final String DEFEXPOSURETIME

The name of the exposure time global.

Constant Field Values

time

private ExposureTimeLeft time

The time parameter, if registered.

Constructor Detail

FractionalExposureTime

public FractionalExposureTime(Map define)

Constructs a new global representing julian date. Providing a properties object that maps the #KEY_BASEJD to 40587 makes this object produce mjd.

Method Detail

rescanned

public 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.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class AbstractParameter

registerParameter

public void registerParameter(Parameter curtime)

Description copied from interface: ParameterDepending

A parameter depending command should drain the necessarry information to get valid out of a parameter value. During rendering, parameter depending commands should receive their data through this method. Note that it is always possible to pile up all the information needed for a single command in a single parameter.

Specified by:

registerParameter in interface ParameterDepending

setValue

public Number setValue(Number val)
                throws UnsupportedOperationException

Sets the fractional exposure time. Exposure time is a read-only variable, therefore this method throws an UnsupportedOperationException.

Specified by:

setValue in interface Value

Throws:

UnsupportedOperationException

getValue

public Number getValue()

Returns the fractinal exposure time already passed. If the required ExposureTimeLeft count-down is not registered, null is returned.

Specified by:

getValue in interface Value
