Constructor & Destructor Documentation

◆ QgsVectorLayerFeaturePool()

QgsVectorLayerFeaturePool::QgsVectorLayerFeaturePool ( QgsVectorLayer * layer )

Creates a new feature pool for layer.

Definition at line 22 of file qgsvectorlayerfeaturepool.cpp.

Member Function Documentation

◆ addFeature()

bool QgsVectorLayerFeaturePool::addFeature	(	QgsFeature &	feature,
		QgsFeatureSink::Flags	flags = `QgsFeatureSink::Flags()`
	)

overridevirtual

Adds a single feature to the sink.

Feature addition behavior is controlled by the specified flags.

See also: addFeatures()

Returns: true in case of success and false in case of failure

Reimplemented from QgsFeatureSink.

Definition at line 30 of file qgsvectorlayerfeaturepool.cpp.

◆ addFeatures()

bool QgsVectorLayerFeaturePool::addFeatures	(	QgsFeatureList &	features,
		QgsFeatureSink::Flags	flags = `QgsFeatureSink::Flags()`
	)

overridevirtual

Adds a list of features to the sink.

Feature addition behavior is controlled by the specified flags.

See also: addFeature()

Returns: true in case of success and false in case of failure

Implements QgsFeatureSink.

Definition at line 68 of file qgsvectorlayerfeaturepool.cpp.

◆ deleteFeature()

void QgsVectorLayerFeaturePool::deleteFeature ( QgsFeatureId fid )

overridevirtual

Removes a feature from this pool.

Implementations will remove the feature from the layer or from the data provider.

Implements QgsFeaturePool.

Definition at line 123 of file qgsvectorlayerfeaturepool.cpp.

◆ updateFeature()

void QgsVectorLayerFeaturePool::updateFeature ( QgsFeature & feature )

overridevirtual

Updates a feature in this pool.

Implementations will update the feature on the layer or on the data provider.

Implements QgsFeaturePool.
