Utility macro to define GetNextFeature() through GetNextRawFeature()

Typedef Documentation

OGRLayerUniquePtr

using OGRLayerUniquePtr = std::unique_ptr<OGRLayer>

Unique pointer type for OGRLayer.

Since

GDAL 3.2

Function Documentation

begin()

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

OGRLayer::begin()

end()

OGRLayer::FeatureIterator end ( OGRLayer *  poLayer )

inline

Return end of feature iterator.
