Methods in this class are used to handle basic operations on vector layers.
QMap< int, QVariant > QgsAttributeMap
Definition: qgsfeature.h:45
A geometry is the spatial representation of a feature.
Definition: qgsgeometry.h:79
The feature class encapsulates a single feature including its id, geometry and a list of field/values...
Definition: qgsfeature.h:136
This class wraps a request for features to a vector layer (or directly its vector data provider)...
Represents a vector layer which manages a vector based data sets.
