Stores metadata about one renderer class.

.. note::

   It's necessary to implement createRenderer() function.
   In C++ you can use QgsRendererMetadata convenience class.

    QgsRendererAbstractMetadata( const QString &name, const QString &visibleName, const QIcon &icon = QIcon() );
%Docstring
Constructor for QgsRendererAbstractMetadata, with the specified ``name``.

The ``visibleName`` argument gives a translated, user friendly string identifying the renderer type.

The ``icon`` argument can be used to specify an icon representing the renderer.
%End
    virtual ~QgsRendererAbstractMetadata();

    QString name() const;
%Docstring
Returns the unique name of the renderer. This value is not translated.

.. seealso:: :py:func:`visibleName`
%End

    QString visibleName() const;
%Docstring
Returns a friendly display name of the renderer. This value is translated.

.. seealso:: :py:func:`name`

    QIcon icon() const;
%Docstring
Returns an icon representing the renderer.

.. seealso:: :py:func:`setIcon`

%Docstring
Sets an ``icon`` representing the renderer.

Returns flags indicating the types of layer the renderer is compatible with.

Returns new instance of the renderer given the DOM element. Returns ``None`` on error.
Pure virtual function: must be implemented in derived classes.  *
%End

    virtual QgsRendererWidget *createRendererWidget( QgsVectorLayer *layer, QgsStyle *style, QgsFeatureRenderer *oldRenderer ) /Factory/;
%Docstring
Returns new instance of settings widget for the renderer. Returns ``None`` on error.

The ``oldRenderer`` argument may refer to previously used renderer (or it is ``None``).
If not ``None``, it may be used to initialize GUI of the widget from the previous settings.
The old renderer does not have to be of the same type as returned by createRenderer().

Adds a renderer to the registry. Takes ownership of the metadata object.

         be added (e.g., a renderer with a duplicate name already exists)

%Docstring
Removes a renderer from registry.

:return: ``True`` if renderer was successfully removed, or ``False`` if matching
         renderer could not be found
%End

Returns the metadata for a specified renderer. Returns ``None`` if a matching
renderer was not found in the registry.
