Methods in this class are used to handle basic operations on vector layers.
virtual bool copyMoveFeatures(QgsVectorLayer *layer, QgsFeatureRequest &request, double dx=0, double dy=0, QString *errorMsg=nullptr) const
Copy and move features with defined translation.
virtual bool saveEdits(QgsVectorLayer *layer) const =0
Should be called, when the features should be committed but the editing session is not ended...
virtual bool startEditing(QgsVectorLayer *layer) const =0
This will be called, whenever a vector layer should be switched to edit mode.
A geometry is the spatial representation of a feature.
Definition: qgsgeometry.h:111
virtual bool stopEditing(QgsVectorLayer *layer, bool allowCancel=true) const =0
Will be called, when an editing session is ended and the features should be committed.
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)...
virtual bool addFeature(QgsVectorLayer *layer, const QgsAttributeMap &defaultValues=QgsAttributeMap(), const QgsGeometry &defaultGeometry=QgsGeometry(), QgsFeature *feature=nullptr) const =0
This method should/will be called, whenever a new feature will be added to the layer.
Represents a vector layer which manages a vector based data sets.
