Class AbstractDataModel

java.lang.Object

oracle.spatial.network.nfe.vis.maps.model.AbstractDataModel

public abstract class AbstractDataModel
extends java.lang.Object

Abstract class to represent editable spatial models. A Spatial is composed by several data sets. Network model: data sets for nodes and links. Topology model: data sets for nodes, edges and faces.
