AddRequest()

bool Maria::ExternalMapTileProvider::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::ExternalMapTileProvider::GetMapEntries ( std::vector< MapEntry > &  mapEntries ) const

overridevirtual

Parameters

mapEntries

Result

Implements Maria::IMapTileProvider.

PendingRequestCount()

int Maria::ExternalMapTileProvider::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 ExternalMapTileProvider::RemoveRequest ( int  tileCacheId, bool  removeNewest  )

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.
