A feature pool is based on a vector layer and caches features.
virtual void updateFeature(QgsFeature &feature)=0
Updates a feature in this pool.

Removes a feature from this pool.
virtual bool addFeature(QgsFeature &feature, QgsFeatureSink::Flags flags=QgsFeatureSink::Flags())
Adds a single feature to the sink.
virtual bool addFeatures(QgsFeatureList &features, QgsFeatureSink::Flags flags=QgsFeatureSink::Flags())=0
Adds a list of features to the sink.
The feature class encapsulates a single feature including its unique ID, geometry and a list of field...
