Detailed Description

Contains details about a sub layer available from a dataset.

This class encapsulates the properties of a single sublayer available from a dataset, according to a specific data provider.

Note: It is possible that multiple data providers may be able to utilize the same underlying sub layer in a single dataset, yet will interpret this layer differently. For instance, a layer in a Geospatial PDF document can be interpreted as either a vector layer by the OGR data provider or a raster layer by the GDAL provider. The providerKey() property can be used to determine the data provider associated with a QgsProviderSubLayerDetails instance.
