## Detailed Description

LEGACY class.

Use GDALDataset in your new code ! This class may be removed in a later release.

This class represents a data source. A data source potentially consists of many layers (OGRLayer). A data source normally consists of one, or a related set of files, though the name doesn't have to be a real item in the file system.

When an OGRDataSource is destroyed, all it's associated OGRLayers objects are also destroyed.

NOTE: Starting with GDAL 2.0, it is NOT safe to cast the handle of a C function that returns a OGRDataSourceH to a OGRDataSource*. If a C++ object is needed, the handle should be cast to GDALDataset*.

Deprecated:

The documentation for this class was generated from the following files:

- ogrsf_frmts.h
- ogrdatasource.cpp

Generated for GDAL by 1.8.9.1.
