Examples of org.openstreetmap.josm.data.osm.OsmPrimitive

org.openstreetmap.josm.data.osm.OsmPrimitive
The base class for OSM objects ( {@link Node}, {@link Way}, {@link Relation}). It can be created, deleted and uploaded to the OSM-Server. Although OsmPrimitive is designed as a base class, it is not to be meant to subclass it by any other than from the package {@link org.openstreetmap.josm.data.osm}. The available primitives are a fixed set that are given by the server environment and not an extendible data stuff. @author imi
