Member Function Documentation

◆ decode()

bool QgsVectorTileMVTDecoder::decode ( const QgsVectorTileRawData rawTileData)

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

Definition at line 40 of file qgsvectortilemvtdecoder.cpp.

◆ layerFeatures()

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.

Definition at line 88 of file qgsvectortilemvtdecoder.cpp.

◆ layerFieldNames()

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()

Definition at line 71 of file qgsvectortilemvtdecoder.cpp.

◆ layers()

QStringList QgsVectorTileMVTDecoder::layers ( ) const

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

Definition at line 57 of file qgsvectortilemvtdecoder.cpp.
