Constructor & Destructor Documentation

QgsVectorTileMVTDecoder::QgsVectorTileMVTDecoder ( const QgsVectorTileMatrixSet & structure )

Constructor for QgsVectorTileMVTDecoder, using the specified tile structure.

QgsVectorTileMVTDecoder::~QgsVectorTileMVTDecoder ( )

default

bool QgsVectorTileMVTDecoder::decode ( const QgsVectorTileRawData & rawTileData )

Tries to decode raw tile data, returns true on success.

QgsVectorTileFeatures QgsVectorTileMVTDecoder::layerFeatures	(	const QMap< QString, QgsFields > &	perLayerFields,
		const QgsCoordinateTransform &	ct,
		const QSet< QString > *	layerSubset = `nullptr`
	)		const

Returns decoded features grouped by sub-layers.

It can only be called after a successful decode()

If layerSubset is specified then only features from the specified layers will be returned.

QStringList QgsVectorTileMVTDecoder::layerFieldNames ( const QString & layerName ) const

Returns a list of all field names in a tile. It can only be called after a successful decode()

QStringList QgsVectorTileMVTDecoder::layers ( ) const

Returns a list of sub-layer names in a tile. It can only be called after a successful decode()
