Package org.gvsig.fmap.mapcontrol

Interface MapControlDrawer

All Superinterfaces:
PrimitivesDrawer
All Known Implementing Classes:
MapControlDrawer2D
public interface MapControlDrawer extends PrimitivesDrawer

Represents a class that can write objects in a map like a raster image, a Geometry or other graphical objects. This class doesn't depend of the dimension of the map (2D or 3D).

The Map Control has to have an instance of this class that can be accessed using the MapControl.getMapControlDrawer() method. When a Map Control is created some tools are added to this component using the MapControl.addBehavior(String, org.gvsig.fmap.mapcontrol.tools.Behavior.Behavior) method. Some of these tools need to draw some objects in the map and they use the MapControlDrawer class to do that.
