Constructor Detail

RaApparent

public RaApparent(Map<String,String> prop)

Constructs a new global representing the actual object's ra.

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

registerTarget

public void registerTarget(TargetDefinition star)

Registers a star to this parameter. The declination of the star is set as this parameter's value.

Specified by:

registerTarget in interface TargetDepending

getForTarget

public Number getForTarget(TargetDefinition star)

Gets the right ascension of the target star, precessed to current equinox.

Specified by:

getForTarget in interface TargetDependingParameter

Specified by:

getForTarget in interface TargetDependingValue

Returns:

A Double holding the target star's right ascension.

setValue

public Number setValue(Number val)
                throws UnsupportedOperationException

Sets the apparent right ascension. The right ascension 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 ra of the actual target. Returns null if the ra has not been set previously.

Specified by:

getValue in interface Value

getUnprecessed

protected Number getUnprecessed(TargetDefinition star)

Returns the catalog value.

getUnprecessed

protected Number getUnprecessed()

Returns the catalog value.

registerParameter

public void registerParameter(Parameter what)

Registers the required additional globals for the ra actual. For this particular object, the julian date and the declination of the target is needed.

Specified by:

registerParameter in interface ParameterDepending

getEpoch

public double getEpoch()

Returns the current epoch in julian yeras.

precess

private Number precess(double alpha,
                       double delta,
                       double jul)

Precesses the right ascension to the jd given in the third parameter.
