Member Function Documentation

MapSourceKind MAP::GoogleMapSource::getSourceKind (   )  const [inline, virtual]

Returns source kind Implements MAP::MapSource.

MAExtent MAP::GoogleMapSource::getTileSize (   )  const [inline, virtual]

Returns tile size Implements MAP::MapSource.

int MAP::GoogleMapSource::getMagnificationMin (   )  const [inline, virtual]

Returns minimum magnification Implements MAP::MapSource.

int MAP::GoogleMapSource::getMagnificationMax (   )  const [inline, virtual]

Returns maximum magnification Implements MAP::MapSource.

void MAP::GoogleMapSource::getTileUrl (  char *  buffer, MapTileCoordinate  tileXY )  [virtual]

Returns URL for retrieving a tile Implements MAP::MapSource.

MapTileCoordinate MAP::GoogleMapSource::lonLatToTile (  LonLat  lonlat, int  magnification )  [virtual]

Converts LonLat to tile coordinates for a tile that contains the lonlat point. Implements MAP::MapSource.

PixelCoordinate MAP::GoogleMapSource::lonLatToPixel (  LonLat  lonlat, int  magnification )  [virtual]

Converts LonLat to a pixel coordinate, in a global pixel grid Implements MAP::MapSource.

LonLat MAP::GoogleMapSource::tileCenterToLonLat (  const int  tileSize, const MapTileCoordinate &  tile, const double  offsetX, const double  offsetY )  [virtual]

Convert tile center plus pixel offset to WGS84 lat/lon. Implements MAP::MapSource.

void MAP::MapSource::requestTile (  const MapTileCoordinate  tileXY, IMapSourceListener *  listener, MapSourceClientData *  clientData )  [inherited]

Returns all tiles required to cover specified rectangle around centerpoint.

void MAP::MapSource::clearQueue (   )  [inherited]

Clears any queued requests

void MAP::MapSource::finishedDownloading (  Downloader *  downloader, MAHandle  data )  [virtual, inherited]

Called when all data has been downloaded. Parameters: downloader  A pointer to the downloader sending this event. data  MAHandle to the binary data resource with the downloaded data. Implements MAUtil::DownloadListener.

void MAP::MapSource::downloadCancelled (  Downloader *  downloader  )  [virtual, inherited]

Called if the download has been cancelled. Parameters: downloader  A pointer to the downloader sending this event. Implements MAUtil::DownloadListener.

void MAP::MapSource::error (  Downloader *  downloader, int  code )  [virtual, inherited]

Called if an error occured. Parameters: downloader  A pointer to the downloader sending this event. code  The error code describing the error. See CONNERR . Implements MAUtil::DownloadListener.

virtual void MAUtil::DownloadListener::notifyProgress (  Downloader *  downloader, int  downloadedBytes, int  totalBytes )  [virtual, inherited]

Called when some data has been downloaded to notify about the progress of the download. Parameters: downloader  A pointer to the downloader sending this event. downloadedBytes  The amount of bytes downloaded. totalBytes  The amount of bytes to be downloaded.

virtual bool MAUtil::DownloadListener::outOfMemory (  Downloader *  downloader  )  [virtual, inherited]

Called if the Downloader runs out of memory. Try to free some resource memory. If you managed to free some, return true to make the Downloader try again. If you can't free any more, return false to make the Downloader fail with CONNERR_DOWNLOADER_OOM. The default implementation does nothing and returns false.
