Method Detail

getInstance

public static SimbadGateway getInstance()

Get a reference to the gateway object (singleton).

getStarFromId

public Star getStarFromId(java.lang.String id,
                          java.lang.String rootURL,
                          javax.swing.JTextArea textarea)

Use a Simbad identity query as a REST web service: HTTP request responds with XML VOTable. If rootURL is not null and not empty, the encoded id will simply be appended to it: do that if the call has to be via some server code, eg for an applet: rootURL = "http://mydomain/simbadi.jsp?id=" and then the JSP must be written to make the real request to "http://simbad.u-strasbg.fr/simbad/sim-id?Ident=" + id + "&output.format=VOTable". If textarea is not null it will display the VOTable response.

searchCone

public java.util.List<Star> searchCone(SkyPoint centre,
                                       double radiusDegs,
                                       java.lang.String rootURL,
                                       javax.swing.JTextArea textarea)

Use a Simbad coordinate query as a REST web service: HTTP request responds with XML VOTable. If rootURL is not null and not empty, search parameters will simply be appended to it: do that if the call has to be via some server code, eg for an applet: rootURL = "http://mydomain/simbadc.jsp" and then the JSP must be written to make the real request (passing on the parameters shown here) to
"http://simbad.u-strasbg.fr/simbad/sim-coo?output.format=VOTable" +
"&Coord=" + centre.getRA ().toDegrees () + centre.getDec ().toDegrees () +
"&CooEpoch=" + centre.getEpoch ().getYear () +
"&Radius=" + radiusDegs + "&Radius.unit=deg&list.idcat=Tycho,HIP2,GSC"
If textarea is not null it will display the VOTable response.
