Member Function Documentation

◆ AddRequest()

bool Maria::NormalMapProvider::AddRequest	(	const MapContentQuery &	request,
		FullTileId	tileId,
		std::shared_ptr< ITileDataResponseTarget >	responseTarget
	)

overridevirtual

Add request to provider. Returns false if provider queue is full.

Parameters

request	Tile request
tileId	Tile cache id and tile id of tile
responseTarget	Call to process response from tile providers

Returns: true on success, false if unable to add request

Implements Maria::IMapTileProvider.

◆ GetMapEntries()

void Maria::NormalMapProvider::GetMapEntries ( std::vector< MapEntry > & mapEntries ) const

overridevirtual

Get a list of map entries available to this data provider.

Implements Maria::IMapDataProvider.

◆ GetMapEntry()

bool Maria::NormalMapProvider::GetMapEntry	(	const MapContentQuery &	mapQuery,
		MapEntry &	mapEntry,
		unsigned long	timeout
	)

overridevirtual

Get a map catalog entry from a map query. This method should fill out the provided mapEntry with the resolved data for the given mapQuery.

The method should return true on success, and false on failure.

The method should block until a response can be given, but at most timeout ms. If timeout = 0, it may block indefinitely.

Implements Maria::IMapDataProvider.

◆ GetTileData()

std::shared_ptr< MariaProtobuf::FetchMapReplyMessage > Maria::NormalMapProvider::GetTileData	(	const GenerateMapTileRequest &	req,
		unsigned long	timeout_ms
	)

overridevirtual

Get map tile data from map query. This method should return a FetchMapReply with tile data or a valid error code for the given mapQuery.

The method should block until a response can be given, but at most timeout ms. If timeout = 0, it may block indefinitely.

Implements Maria::IMapDataProvider.

◆ PendingRequestCount()

int Maria::NormalMapProvider::PendingRequestCount ( int tileCacheId = -1 ) const

inlineoverridevirtual

Count of pending requests for specified tile cache.

Parameters

tileCacheId Tile cache id

Returns: Number of pending requests

Implements Maria::IMapTileProvider.

◆ RemoveRequest()

FullTileId Maria::NormalMapProvider::RemoveRequest	(	int	tileCacheId,
		bool	removeNewest = `false`
	)

overridevirtual

Try to remove request from queue associated with a specific tile cache.

Parameters

tileCacheId	Tile cache id
removeNewest	If true, remove newest request. Of false, remove oldest request

Returns: Id of removed tile, InvalidTileId on failure

Implements Maria::IMapTileProvider.

◆ setAllowOverzoom()

void Maria::NormalMapProvider::setAllowOverzoom ( bool allowOverzoom )

inline

Allow oversampling of data. If true, we will always get a data tile, even if the underlying data is lower resolution, it will simply be scaled up to fit the requested tile. If this flag is false, we return OutOfResolution if the requested tile has 2x the resolution (or more) of the maximum data resolution.

◆ setGenerateMissingTiles()

void Maria::NormalMapProvider::setGenerateMissingTiles ( bool generateEmptyTiles )

inline

Generate dummy tiles if no data. If no data could be found for this tile, a dummy tile with [0,0,1] normal vectors is returned.
