Class IlvMapDataSourceModel

java.lang.Object
  javax.swing.tree.DefaultTreeModel
      ilog.views.maps.datasource.IlvMapDataSourceModel

All Implemented Interfaces:

IlvPersistentObject, Serializable, TreeModel

public class IlvMapDataSourceModel
extends DefaultTreeModel
implements IlvPersistentObject

The IlvMapDataSourceModel is a tree model used to display data sources in a tree. A data source model can be attached to a IlvManager through a IlvMapDataSourceProperty in order to be saved in an .ivl file. The following code retrieves the data source model from an IlvManager and inserts a data source.

  IlvMapDataSourceModel model = 
    IlvMapDataSourceProperty.GetMapDataSourceModel(manager);
 IlvMapDataSource reader = new IlvShapeDataSource("shapeFile.shp", true);
 model.insert(reader);
