Class: QgsFeatureSink¶

An interface for objects which accept features via addFeature(s) methods.

Class Hierarchy¶

`QgsVectorLayer`	Represents a vector layer which manages a vector based data sets.
`QgsFeatureStore`	A container for features with the same fields and crs.
`QgsProxyFeatureSink`	A simple feature sink which proxies feature addition on to another feature sink.
`QgsRemappingProxyFeatureSink`	A `QgsFeatureSink` which proxies incoming features to a destination feature sink, after applying transformations and field value mappings.
`QgsSpatialIndex`	A spatial index for `QgsFeature` objects.
`QgsVectorDataProvider`	This is the base class for vector data providers.
`QgsVectorFileWriter`	A convenience class for writing vector layers to disk based formats (e.g. Shapefiles, GeoPackage).
`QgsVectorLayerExporter`	A convenience class for exporting vector layers to a destination data provider.
`QgsVectorLayerJoinBuffer`	Manages joined fields for a vector layer.
`QgsFeaturePool`	A feature pool is based on a vector layer and caches features.

Methods

`addFeature`	Adds a single feature to the sink.
`addFeatures`	Adds a list of features to the sink.
`flushBuffer`	Flushes any internal buffer which may exist in the sink, causing any buffered features to be added to the sink's destination.
`lastError`	Returns the most recent error encountered by the sink, e.g. when a call to `addFeatures()` returns `False`.

Attributes

class qgis.core.QgsFeatureSink[source]¶

Bases: object

addFeature(self, feature: QgsFeature, flags: QgsFeatureSink.Flags | QgsFeatureSink.Flag = QgsFeatureSink.Flags()) → bool[source]¶

Adds a single feature to the sink. Feature addition behavior is controlled by the specified flags.
