QgsProxyFeatureSink (QgsFeatureSink *sink) | |
Constructs a new QgsProxyFeatureSink which forwards features onto a destination sink. More... | |
bool | addFeature (QgsFeature &feature, QgsFeatureSink::Flags flags=QgsFeatureSink::Flags()) override |
Adds a single feature to the sink. More... | |
bool | addFeatures (QgsFeatureIterator &iterator, QgsFeatureSink::Flags flags=QgsFeatureSink::Flags()) override |
Adds all features from the specified iterator to the sink. More... | |
bool | addFeatures (QgsFeatureList &features, QgsFeatureSink::Flags flags=QgsFeatureSink::Flags()) override |
Adds a list of features to the sink. More... | |
QgsFeatureSink * | destinationSink () |
Returns the destination QgsFeatureSink which the proxy will forward features to. More... | |
![]() | |
virtual | ~QgsFeatureSink ()=default |
virtual bool | flushBuffer () |
Flushes any internal buffer which may exist in the sink, causing any buffered features to be added to the sink's destination. More... | |

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 QgsProxyFeatureSink can instead be returned which forwards features on to the destination sink. The proxy sink can be safely deleted without affecting the destination sink.
