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. |

void position(double raJ2000, double deJ2000)
raJ2000
- Right ascension in degrees J2000deJ2000
- Declination in degrees J2000void pixel(double pixValue)
pixValue
- pixel value under the mouse
