## Detailed Description

Classes related to registration of format support, and opening datasets.

## Function Documentation

OGRLayer::FeatureIterator begin | ( | OGRLayer * | poLayer | ) |
| inline

Return begin of feature iterator.

Using this iterator for standard range-based loops is safe, but due to implementation limitations, you shouldn't try to access (dereference) more than one iterator step at a time, since the std::unique_ptr<OGRFeature> reference is reused.

Only one iterator per layer can be active at a time.

Since
  GDAL 2.3
