public String buildLocalFilePath ( int x , int y , int z , String fileExt ) { if ( localTilePathBuilder == null ) { localTilePathBuilder = new TilePathBuilder ( localCacheDir ) ; } return localTilePathBuilder . buildTilePath ( x , y , z , fileExt ) ; }
acts the same as the buildfilepath method , but works for a local directory specified in the properties .
