Map Class Hierarchy

MapLayer define common map operation, like setCenter, Zoom in, Zoom out, Pan Direction and coordinates conversion (from Map to screen and vice versa) and it’s a common base class for all digital map.

MapLayerContainer is container classes; manage a collection of Map layers allow them setCenter, Zoom In, Zoom out and Pan Direction together.


DigitalMap introduces Map Services like Geocoding, Reverse Geocoding and Routing service. It supports incorporate different Map Services implementation.


RasterMap deals with online, stored map images tiles, it support multi-threads and also provide listener to monitor the progress of downloading or reading map image tiles.


VectorMap is a subclass of RasterMap, so it supports all functions provided by RasterMap, instead of downloading image tiles from map server or reading map image tiles from local files, Vector renders map image tile from MapInfo compatible vector map file also supports Geoset which managers multiple map feature layers.
