Constructs a new
QgsProxyFeatureSinkwhich forwards features onto a destination
A simple feature sink which proxies feature addition on to another feature sink.
This class is designed to allow factory methods which always return new QgsFeatureSink objects. Since it is not always possible to create an entirely new QgsFeatureSink (e.g. if the feature sink is a layer’s data provider), a new
QgsProxyFeatureSinkcan instead be returned which forwards features on to the destination sink. The proxy sink can be safely deleted without affecting the destination sink.
New in version 3.0.
