class QgsRendererAbstractMetadata
{
%Docstring
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`
%End

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

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

    void setIcon( const QIcon &icon );
%Docstring
Sets an ``icon`` representing the renderer.

.. seealso:: :py:func:`icon`

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

    virtual QgsFeatureRenderer *createRenderer( QDomElement &elem, const QgsReadWriteContext &context ) = 0 /Factory/;
%Docstring
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().
When using ``oldRenderer`` make sure to make a copy of it - it will be deleted afterwards.

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

:param metadata: renderer metadata

:return: ``True`` if renderer was added successfully, or ``False`` if renderer could not
         be added (e.g., a renderer with a duplicate name already exists)

%Docstring
Removes a renderer from registry.

:param rendererName: name of renderer to remove from registry

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

    QgsRendererAbstractMetadata *rendererMetadata( const QString &rendererName );

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

Returns a list of available renderers which are compatible with a specified layer.
