All Implemented Interfaces:

Serializable, TargetDependingCommand, EnvironmentCommand

public class FollowRoof
extends CommandEvent
implements EnvironmentCommand, TargetDependingCommand

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

FollowRoof

public FollowRoof(Object src)

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

FollowRoof

public FollowRoof(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.
