class QgsLayerDefinition
{
%Docstring
The QgsLayerDefinition class holds generic methods for loading/exporting QLR files.

QLR files are an export of the layer xml including the style and datasource location.  There is no link
to the QLR file once loaded.  Consider the QLR file a mini project file for layers and styles.  QLR
files also store the layer tree info for the exported layers, including group information.

  public:
    static bool loadLayerDefinition( const QString &path, QgsProject *project, QgsLayerTreeGroup *rootGroup, QString &errorMessage /Out/ );
%Docstring
Loads the QLR at path into QGIS.  New layers are added to given project into layer tree specified by rootGroup
%End
    static bool loadLayerDefinition( QDomDocument doc,  QgsProject *project, QgsLayerTreeGroup *rootGroup, QString &errorMessage /Out/, QgsReadWriteContext &context );

Loads the QLR from the XML document.  New layers are added to given project into layer tree specified by rootGroup
%End

Export the selected layer tree nodes to a QLR file

    static bool exportLayerDefinition( QDomDocument doc, const QList<QgsLayerTreeNode *> &selectedTreeNodes, QString &errorMessage /Out/, const QgsReadWriteContext &context );

Export the selected layer tree nodes to a QLR-XML document

%Docstring
Returns the given layer as a layer definition document
Layer definitions store the data source as well as styling and custom properties.

Layer definitions can be used to load a layer and styling all from a single file.

This is a low-level routine that does not write layer tree.

.. seealso:: :py:func:`exportLayerDefinition`

    static QList<QgsMapLayer *> loadLayerDefinitionLayers( QDomDocument &document, QgsReadWriteContext &context ) /Factory/;
%Docstring
Creates new layers from a layer definition document.
This is a low-level routine that does not resolve layer ID conflicts, dependencies and joins

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

    static QList<QgsMapLayer *> loadLayerDefinitionLayers( const QString &qlrfile ) /Factory/;
%Docstring
Creates new layers from a layer definition file (.QLR)
This is a low-level routine that does not resolve layer ID conflicts, dependencies and joins
