[mapserver-users] Layer Query

[Lime, Steve D (DNR)]

Your syntax looks off. Below a snippet (in Perl) from RFC 65 (http://www.mapserver.org/development/rfc/ms-rfc-65.html). It applies generally to all languages.

my $rect = new mapscript::rectObj(420000, 5120000, 582000, 5200000);
$layer->queryByRect($map, $rect); # layer is left open after this operation

for(my $i=0; $i<$layer->getNumResults(); $i++) {
       my $shape = $layer->getShape($layer->getResult($i));
       ...
}

Subject: [mapserver-users] Layer Query

Hello, I am researching and trying to use queries layers of mapserver, mapscript through, but not how to obtain, if possible, the result information.
I do not use wms

My java code

mapObj map = new mapObj("/home/gaston/maps/map/map.map")    ;
layerObj layer = map.getLayerByName("Info");
//centerP es el putno
layer.queryByPoint(map,new pointObj(centerP.getX(),centerP.getY(),0), mapscriptConstants.MS_SINGLE, 10);
layer.open();
resultCacheObj res =layer.getResults();
            for(int i=0 ;i<layer.getNumResults();i++){ /
                shapeObj feature = layer.getShape(res.getResult(i));
               //Aca no se q hacer
            }


My .map
