Methods in this class are used to handle basic operations on vector layers.
A geometry is the spatial representation of a feature.
Definition: qgsgeometry.h:106
#define SIP_INOUT
Definition: qgis_sip.h:64
The feature class encapsulates a single feature including its id, geometry and a list of field/values...
Definition: qgsfeature.h:55
QMap< int, QVariant > QgsAttributeMap
Definition: qgsattributes.h:38
This class wraps a request for features to a vector layer (or directly its vector data provider)...
#define SIP_OUT
Definition: qgis_sip.h:51
Represents a vector layer which manages a vector based data sets.
