TileChildrenAvailability
Possible availability states for a tile's children.
An abstract base class for tiled scene data provider indices.
QgsAbstractTiledSceneIndex & operator=(const QgsAbstractTiledSceneIndex &other)=delete
virtual QVector< long long > childTileIds(long long id) const =0
Returns a list of the tile IDs of any children for the tile with matching id.
virtual long long parentTileId(long long id) const =0
Returns the tile ID of the parent tile of the tile with matching id, or -1 if the tile has no parent.
virtual ~QgsAbstractTiledSceneIndex()
virtual QgsTiledSceneTile rootTile() const =0
Returns the root tile for the index.
virtual QByteArray fetchContent(const QString &uri, QgsFeedback *feedback=nullptr)=0
Fetches index content for the specified uri.
virtual bool fetchHierarchy(long long id, QgsFeedback *feedback=nullptr)=0
Populates the tile with the given id by fetching any sub datasets attached to the tile.
virtual QgsTiledSceneTile getTile(long long id)=0
Returns the tile with matching id, or an invalid tile if the matching tile is not available.
QgsAbstractTiledSceneIndex(const QgsAbstractTiledSceneIndex &other)=delete
virtual Qgis::TileChildrenAvailability childAvailability(long long id) const =0
Returns the availability for a tile's children.
virtual QVector< long long > getTiles(const QgsTiledSceneRequest &request)=0
Returns the tile IDs which match the given request.
Base class for feedback objects to be used for cancellation of something running in a worker thread.
An index for tiled scene data providers.
Tiled scene data request.
Represents an individual tile from a tiled scene data source.
