public class MapContext
extends org.gvsig.tools.dispose.impl.AbstractDisposable
implements org.cresques.geo.Projected, org.gvsig.tools.persistence.Persistent, org.gvsig.tools.observer.Observer

The MapContext class represents the model and a part of the control and view around graphical layers used by MapControl.

An instance of MapContext is made up with:

• a hierarchy of FLayers nodes
• a GraphicLayer layer
• a ViewPort
• an EventButter
• some LegendListeners
• some LayerDrawingListeners
• some ErrorListeners
