Class: QgsVectorLayerFeatureIterator

class qgis.core.QgsVectorLayerFeatureIterator(source: QgsVectorLayerFeatureSource, ownSource: bool, request: QgsFeatureRequest)

Bases: qgis._core.QgsAbstractFeatureIteratorFromSourceQgsVectorLayerFeatureSourceBase

Enums

Methods

close	end of iterating: free the resources / lock
deref
fetchFeature	fetch next feature, return true on success
filterRectToSourceCrs
geometryToDestinationCrs
isValid
iteratorClosed
nextFeatureFilterExpression	Overrides default method as we only need to filter features in the edit buffer while for others filtering is left to the provider implementation.
nextFeatureFilterFids
prepareSimplification	Setup the simplification of geometries to fetch using the specified simplify method
ref
rewind	reset the iterator to the starting position
