class QgsEmbeddedSymbolRenderer : QgsFeatureRenderer
{
%Docstring(signature="appended")
A vector feature renderer which uses embedded feature symbology to
render per-feature symbols.
This renderer can be used for vector layers with a data provider which
supports the :py:class:`QgsVectorDataProvider`.FeatureSymbology
capability, where the dataset has embedded information on how each
feature should be rendered.

QgsEmbeddedSymbolRenderer( QgsSymbol *defaultSymbol /Transfer/ );
%Docstring
Constructor for QgsEmbeddedSymbolRenderer.
The ``defaultSymbol`` will be used to render any feature without
embedded symbology. Ownership of ``defaultSymbol`` is transferred to the
renderer.

Sets the default ``symbol`` which will be rendered for any feature which

Creates a new embedded symbol renderer from an XML ``element``, using
the supplied read/write ``context``.
The caller takes ownership of the returned renderer.
