class QgsVectorLayerTools : QObject
{
%Docstring
Methods in this class are used to handle basic operations on vector layers.
With an implementation of this class, parts of the application can ask for
an operation to be done and the implementation will then take care of it.

Reimplement this class, if you need to have custom checks or GUI elements
in your application.

%Docstring
This method should/will be called, whenever a new feature will be added to the layer

:param layer: The layer to which the feature should be added
:param defaultValues: Default values for the feature to add
:param defaultGeometry: A default geometry to add to the feature
:param feature: Updated feature after adding will be written back to this

:return: True in case of success, False if the operation failed/was aborted

TODO QGIS 3: remove const qualifier
%End

    virtual bool startEditing( QgsVectorLayer *layer ) const = 0;
%Docstring
This will be called, whenever a vector layer should be switched to edit mode. Check the providers
capability to edit in here.
If successful layer->startEditing() will be called and true returned.

:param layer: The layer on which to start an edit session

:return: True, if the editing session was started

TODO QGIS 3: remove const qualifier
%End

    virtual bool stopEditing( QgsVectorLayer *layer, bool allowCancel = true ) const = 0;
%Docstring
Will be called, when an editing session is ended and the features should be committed.
Appropriate dialogs should be shown like

:param layer: The layer to commit
:param allowCancel: True if a cancel button should be offered

:return: True if successful

TODO QGIS 3: remove const qualifier
%End

    virtual bool saveEdits( QgsVectorLayer *layer ) const = 0;
%Docstring
Should be called, when the features should be committed but the editing session is not ended.

:param layer: The layer to commit

:return: True if successful

TODO QGIS 3: remove const qualifier
%End

    virtual bool copyMoveFeatures( QgsVectorLayer *layer, QgsFeatureRequest &request /In,Out/, double dx = 0, double dy = 0, QString *errorMsg /Out/ = 0 ) const;
%Docstring
Copy and move features with defined translation.

:param layer: The layer
:param request: The request for the features to be moved. It will be assigned to a new feature request with the newly copied features.
:param dx: The translation on x
:param dy: The translation on y
:param errorMsg: If given, it will contain the error message

:return: True if all features could be copied.
