virtual void updateFeature(QgsFeature &feature)=0
Updates a feature in this pool.
A feature pool based on a vector data provider.
A feature pool is based on a vector layer and caches features.
virtual bool addFeature(QgsFeature &feature, QgsFeatureSink::Flags flags=QgsFeatureSink::Flags())
Adds a single feature to the sink.
virtual void deleteFeature(QgsFeatureId fid)=0
Removes a feature from this pool.
virtual bool addFeatures(QgsFeatureList &features, QgsFeatureSink::Flags flags=QgsFeatureSink::Flags())=0
Adds a list of features to the sink.
Represents a vector layer which manages a vector based data sets.
