All Implemented Interfaces:

Serializable, AdapterCommand, TargetDependingCommand

public class FindAdapter
extends CommandEvent
implements AdapterCommand, TargetDependingCommand

The find command. It is an adapter command because the field-of-view camera is part of the adapter. This command provides a list of stars expected within the field of view. Each star is listed on a command line with its current position, brightness (Johnson V) and color index B-V. The first star in the list is always the target star.

Constructor Detail

FindAdapter

public FindAdapter(Object src)

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

FindAdapter

public FindAdapter(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 view)

Calculates the command line from the properties. For this command, the map handed over must be a StarDescription with an additional key ReservedConstants.FOV. The value mapped to this key is a list of StarDescription objects, each representing a star in the field of view. Note that the first entry in this list is always the target 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 field-of-view stars. The first array element is always the target star.

getDec

public double[] getDec()

Returns the declination of the field-of-view stars. The first array element is always the target star.

getMag

public float[] getMag()

Returns the V-magnitude of the field-of-view stars. The first array element is always the target star.

getBV

public float[] getBV()

Returns the color index B-V of the field-of-view stars. The first array element is always the target star.
