Member Function Documentation

◆ addFeature()

bool QgsFeatureStore::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.

addFeatures()
Returns
true in case of success and false in case of failure

Reimplemented from QgsFeatureSink.

Definition at line 35 of file qgsfeaturestore.cpp.

◆ addFeatures()

bool QgsFeatureStore::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 43 of file qgsfeaturestore.cpp.

int QgsFeatureStore::count ( ) const
inline

Returns the number of features contained in the store.

Definition at line 70 of file qgsfeaturestore.h.

◆ crs()

QgsCoordinateReferenceSystem QgsFeatureStore::crs ( ) const
inline

Returns the store's coordinate reference system.
