static unsigned index
Container of fields for a vector layer.
Definition: qgsfield.h:173
A convenience class for writing vector files to disk.
The feature class encapsulates a single feature including its id, geometry and a list of field/values...
Definition: qgsfeature.h:119
The QGis class provides vector overlay analysis functions.
Represents a vector layer which manages a vector based data sets.
