Caching query result?

[Frederico Lucca]

Lorenzo,

I have a source in java.
It's important when you invoke, to set the scale as the same you are in the map.
It works fine.

public shapeObj getInfo(String name, double x, double y, int range){
        
        shapeObj shape = null;
        pointObj point = new pointObj(x,y,0);
        layerObj layer = map.getLayerByName(name);
        layer.setTemplate("whatever");
        layer.setSizeunits(mapscript.MS_METERS);
        layer.setToleranceunits(mapscript.MS_METERS);
        layer.setTolerance(range);
        
        if(layer.queryByPoint(map, point, mapscript.MS_SINGLE,
-1)==mapscript.MS_SUCCESS){
            
            resultCacheObj results = layer.getResults();
            
            if (results.getNumresults()>0){
                
                layer.open();
                
                resultCacheMemberObj result = results.getResult(0);
                
                shape=new shapeObj(layer.getType());
               
layer.getShape(shape,result.getTileindex(),result.getShapeindex());
                
                layer.close();
                
            }
        }
        
        return shape;
}
