Class: QgsFeatureIterator

class qgis.core.QgsFeatureIterator

Bases: sip.wrapper

Construct invalid iterator

QgsFeatureIterator(iter: QgsAbstractFeatureIterator) Construct a valid iterator

QgsFeatureIterator(fi: QgsFeatureIterator) Copy constructor copies the iterator, increases ref.count

Wrapper for iterator of features from vector data provider or vector layer

Methods

close

rtype

bool

compileFailed

Indicator if there was an error when sending the compiled query to the server.

compileStatus

Returns the status of expression compilation for filter expression requests.

isClosed

find out whether the iterator is still valid or closed already

isValid

Will return if this iterator is valid.

nextFeature

param f

rewind

rtype

bool

close(self) → bool
Return type

bool

compileFailed(self) → bool

Indicator if there was an error when sending the compiled query to the server. This indicates that there is something wrong with the expression compiler.
