org.geomajas.layer.tile.InternalTile

General definition for a tile that is used internally on the server-side. When a tile needs to be send to the client, it must first be converted to a DTO tile. A tile is defined by creating a rectangular grid in map coordinates based on the maximum extent of the layer. This requires a transformation of this maximum extent from layer coordinates to map coordinates.
