[mapserver-users] classindex

[Matt Carlson]

i got this off of the mailing list archives for changes with mapserver 3.5.

- Draw() method of pointObj, RectObj take class_index instead
  of class_name as argument
   pointObj->Draw(map, layer, img, class_index, label_string)
   rectObj->Draw(map, layer, img, class_index, label_string)

how do i get class_index of a mapscript created class, or any class for that
matter?  i browsed through the source and the only reference to classindex i
could find was from the shapeObj.  why was this changed?

code:

###  create a layer ##
    $layer = new layerObj($map);
    $layer->{name} = "bmpl_".$bmpref;
    $layer->{type} = $mapscript::MS_POINT;
    $layer->{status} = $mapscript::MS_ON;

    ### layer classes ###

    $class = new classObj($layer);
    $class->{name} = 'bmcl_'.$bmpref;
    $symx = $map->getSymbolByName($bmpref);
    $class->{symbol} = $symx;

    @latpnts = split(/w/,$latclass{$bmpref});
    @lonpnts = split(/w/,$lonclass{$bmpref});

    ## point object ## loop through each set of points
    for ($k=0; $k<=$#latpnts ;$k++){
      $point = new pointObj();
      $point->{x} = @lonpnts[$k];
      $point->{y} = @latpnts[$k];
      $point->draw($map,$layer,$img,???????????????????????????,undef);
    }
