All Implemented Interfaces:

ParameterDepending, Serializable, InitializerDepending, TelescopeCommand

public class PositionTelescope
extends CommandEvent
implements TelescopeCommand, ParameterDepending, InitializerDepending

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

PositionTelescope

public PositionTelescope(Object src)

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

PositionTelescope

public PositionTelescope(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.
