java.lang.Object
  com.bbn.openmap.util.cacheHandler.CacheHandler
      com.bbn.openmap.dataAccess.mapTile.StandardMapTileFactory
          com.bbn.openmap.dataAccess.mapTile.DebugMapTileFactory

All Implemented Interfaces:

MapTileFactory, PropertyConsumer

public class DebugMapTileFactory
extends StandardMapTileFactory

A simple MapTileFactory that returns empty tiles with labels showing zoom level and x, y coords, and borders. This does the same thing as enabling the MAPTILE_DEBUGGING logger flag, but can be attached to a MapTileLayer which can be turned off and on.

The properties for the layer looke like this (with tileDebug as an example prefix):

 tileDebug.class=com.bbn.openmap.layer.imageTile.MapTileLayer
 tileDebug.prettyName=Map Tile Information
 tileDebug.tileFactory=com.bbn.openmap.dataAccess.mapTile.DebugMapTileFactory

Description copied from class: StandardMapTileFactory

Called to load cache object from data source, when not found in cache.

Overrides:

load in class StandardMapTileFactory

Parameters:

key - cache key

x - uv x coordinate

y - uv y coordinate

zoomLevel - zoom level for tile to load

proj - passed solely to enable checking if the projection of the tiles matches the rendered projection.

Returns:

CacheObject returned from cache, null if not found
