QgsSpatialIndexData::QgsSpatialIndexData ( const QgsFeatureIterator &  fi, QgsFeedback *  feedback = nullptr  )

inlineexplicit

Constructor for QgsSpatialIndexData which bulk loads features from the specified feature iterator fi.

The optional feedback object can be used to allow cancellation of bulk feature loading. Ownership of feedback is not transferred, and callers must take care that the lifetime of feedback exceeds that of the spatial index construction.
