Class MapElement

java.lang.Object

org.oscim.core.GeometryBuffer

org.oscim.core.MapElement

public class MapElement
extends GeometryBuffer

The MapElement class is a reusable container for a geometry with tags.

MapElement is created by TileDataSource(s) and passed to MapTileLoader via ITileDataSink.process(). This is just a buffer that belongs to TileDataSource, so don't keep a reference to it when passed as parameter or make sure to use a copy.
