virtual bool deleteFeature(QgsFeatureId fid)
Delete a feature from the layer (but does not commit it)
virtual bool renameAttribute(int attr, const QString &newName)
Renames an attribute field (but does not commit it)
virtual bool deleteFeatures(const QgsFeatureIds &fid)
Deletes a set of features from the layer (but does not commit it)
virtual bool addAttribute(const QgsField &field)
Adds an attribute field (but does not commit it) returns true if the field was added.
virtual bool addFeatures(QgsFeatureList &features)
Insert a copy of the given features into the layer (but does not commit it)
virtual bool changeAttributeValues(QgsFeatureId fid, const QgsAttributeMap &newValues, const QgsAttributeMap &oldValues)
Changes values of attributes (but does not commit it).
virtual bool isModified() const
Returns true if the provider has been modified since the last commit.
virtual bool addFeature(QgsFeature &f)
Adds a feature.
virtual void rollBack()
Stop editing and discard the edits.
virtual bool commitChanges(QStringList &commitErrors)
Attempts to commit any changes to disk.
virtual bool deleteAttribute(int attr)
Deletes an attribute field (but does not commit it)
virtual bool changeAttributeValue(QgsFeatureId fid, int field, const QVariant &newValue, const QVariant &oldValue=QVariant())
Changed an attribute value (but does not commit it)
virtual bool changeGeometry(QgsFeatureId fid, const QgsGeometry &geom)
Change feature's geometry.
Undo command for vector layer in transaction group mode.
Represents a vector layer which manages a vector based data sets.
