Constructor Detail

StarCommand

protected StarCommand(Object src,
                      String type,
                      long time)

Constructs a move telescope command. Only the header is fully qualified with the provided argumnets. The command line can only be retrieved after a DTDConstants.OBJECT element has been registered to this command.

MessageEvent.isValid()

Method Detail

registerTargetProperties

public void registerTargetProperties(Object aim)

Calculates the command line from the star description delivered in the DTDConstants.OBJECT DOM-element. It uses the DTDConstants.POSITION element within the star element to derive the principal ra and dec from the star.

Specified by:

registerTargetProperties in interface TargetDependingCommand

getLine

public String[] getLine()

Returns the command line of the move telescope command.

Specified by:

getLine in class MessageEvent

Returns:

An array containing all command lines.

parseLine

public boolean parseLine(String[] all)

Parse the command line into ra and dec of the move command.

Specified by:

parseLine in class MessageEvent

Returns:

True, if parsing was successful.

getRa

public double getRa()

Returns the right ascension of the target star.

getDec

public double getDec()

Returns the declination of the target star.

getMag

public float getMag()

Returns the V-magnitude of the target star.

getBV

public float getBV()

Returns the color index B-V of the target star.

getStar

public Star getStar()

Returns the ra de mag v as a star description.

additionalCommands

public abstract void additionalCommands(List<String> tokens)

Only the additional command line parameters to parse after the four star parameters.
