All Implemented Interfaces:

ParameterDepending, Serializable, EnvironmentCommand

public class PositionRoof
extends CommandEvent
implements EnvironmentCommand, ParameterDepending

The move telescope command. It takes dom-elements of type star and scans its general section for the ra, dec, equinox, and proper motions to derive the actual position of the target star from it. The targets ra and dec, both in degrees in the actual equinox, are placed onto the command line.

Constructor Detail

PositionRoof

public PositionRoof(Object src)

Constructs a abort adapter telescope, grabbing the type from the class name and setting the command time to the current system time.

PositionRoof

public PositionRoof(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.

Method Detail

registerParameter

public void registerParameter(Parameter az)

Registers an parameter set to this command. The parameter handed over is queried for its current value and this focus position is set.

Specified by:

registerParameter in interface ParameterDepending

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 a focus position. The first array element is parsed into a double.

Specified by:

parseLine in class MessageEvent

Returns:

True, if parsing was successful.

getPosition

public double getPosition()

Returns the right ascension of the target star.

setPosition

public void setPosition(double pos)

Sets the focus position.
