Interface VOObserver

public interface VOObserver

Interface between two Virtual Observatory applications, such as Aladin (CDS), VOPlot( VO-India), TOPcat, APT (STScI) to listen current J2000 position and pixel value from another VO application. see also VOApp interface and notably addObserver() method.

Method Summary

void	pixel(double pixValue) The observer method to call on a pixel VO event in order to transmit the current pixel value Generally called by a java mouse event, it is strongly recommended to implemented this method as short as possible.
void	position(double raJ2000, double deJ2000) The observer method to call on a position VO event in order to transmit the current coordinates J2000 position.

Method Detail

position

void position(double raJ2000,
              double deJ2000)

The observer method to call on a position VO event in order to transmit the current coordinates J2000 position. Generally called by a java mouse event, it is strongly recommended to implemented this method as short as possible.

Parameters:

raJ2000 - Right ascension in degrees J2000

deJ2000 - Declination in degrees J2000

pixel

void pixel(double pixValue)

The observer method to call on a pixel VO event in order to transmit the current pixel value Generally called by a java mouse event, it is strongly recommended to implemented this method as short as possible.

Parameters:

pixValue - pixel value under the mouse
