Hi,
I want to write JSNI method that can pass a Java function as
parameter, but that function will not be used by me, but by the
underlying API (OpenLayers in my case).
"Full" JavaScript example:
var tms = OpenLayers.Layer.TMS('My TMS Layer', '', {
serviceVersion: '.',
layername: 'dir1/dir2',
type: 'png',
getURL: overlay_getTileURL, // This function will be called each
time the user moves or zooms on the map
isBaseLayer: true,
visibility:false
});
map.addLayer(tms);
function overlay_getTileURL(bounds) {
// my code
// return URL (string)
}
I have a very complete wrapper for the TMS and Bounds objects, so I
can write in Java:
TMSOptions myTmsOptions = new TMSOptions();
TMS tms = new TMS("My TMS Layer", "", myTmsOptions);
map.addLayer(tms);
What I want to do now is something like this in Java:
myTmsOptions.setGetURL("overlayGetTileUrl);
// Can be in any class, in any package
public String overlayGetTileUrl(Bounds bounds) {
String url = "";
// build a string url
return url;
}
I've looked in the documentation but only found how to call a Java
function for which I already know the name (and the package's name).
I've searched a little in that forum but didn't find something looking
like this.
Is that possible ? If yes, how ?
