Interface VoronoiElementFilter


public interface VoronoiElementFilter

The interface is used to decide when calculating the coverage area of the network elements, if current element should be considered in. TWaverGIS implements voronoi diagram. It can be used to display the area covered by a network element. In an application, it is unnecessary that display all the network elements' coverage area. In TWaverGIS, developers can set a special filter instance to GisNetworkAdapter, and tell TWaverGIS to display the coverage area of the specified kind of elements.


Method Summary
 boolean isVoronoiElement(twaver.Element element)
          Decides if the element's coverage area should be displayed.
