 Sets the list of dependencies.

 \param layers set of QgsMapLayerDependency. Only user-defined dependencies will be added
 :return: false if a dependency cycle has been detected

  signals:

    void statusChanged( const QString &status );
%Docstring
Emit a signal with status (e.g. to be caught by QgisApp and display a msg on status bar)
%End

    void nameChanged();
%Docstring
 Emitted when the name has been changed

.. versionadded:: 2.16
%End

    void crsChanged();
%Docstring
Emit a signal that layer's CRS has been reset
%End

    void repaintRequested( bool deferredUpdate = false );
%Docstring
 By emitting this signal the layer tells that either appearance or content have been changed
 and any view showing the rendered layer should refresh itself.
 If ``deferredUpdate`` is true then the layer will only be repainted when the canvas is next
 re-rendered, and will not trigger any canvas redraws itself.
%End

    void recalculateExtents() const;
%Docstring
This is used to send a request that any mapcanvas using this layer update its extents
%End

    void dataChanged();
%Docstring
Data of layer changed
%End

    void blendModeChanged( QPainter::CompositionMode blendMode );
%Docstring
Signal emitted when the blend mode is changed, through QgsMapLayer.setBlendMode()
%End

    void rendererChanged();
%Docstring
 Signal emitted when renderer is changed.
.. seealso:: styleChanged()
%End

    void styleChanged();
%Docstring
 Signal emitted whenever a change affects the layer's style. Ie this may be triggered
 by renderer changes, label style changes, or other style changes such as blend
 mode or layer opacity changes.
.. versionadded:: 2.16
.. seealso:: rendererChanged()
%End

    void legendChanged();
%Docstring
 Signal emitted when legend of the layer has changed
.. versionadded:: 2.6
%End

    void configChanged();
%Docstring
 Emitted whenever the configuration is changed. The project listens to this signal
 to be marked as dirty.
%End

    void dependenciesChanged();
%Docstring
 Emitted when dependencies are changed.
%End

    void willBeDeleted();
%Docstring
 Emitted in the destructor when the layer is about to be deleted,
 but it is still in a perfectly valid state: the last chance for
 other pieces of code for some cleanup if they use the layer.
.. versionadded:: 3.0
%End

    void autoRefreshIntervalChanged( int interval );
%Docstring
 Emitted when the auto refresh interval changes.
.. seealso:: setAutoRefreshInterval()
.. versionadded:: 3.0
%End

    void metadataChanged();
%Docstring
 Emitted when the layer's metadata is changed.
 \see setMetadata()
 \see metadata()

  protected:
    virtual void setExtent( const QgsRectangle &rect );
%Docstring
Set the extent
%End

    void setValid( bool valid );
%Docstring
Set whether layer is valid or not - should be used in constructor.
%End

 Called by writeLayerXML(), used by children to write state specific to them to
  project files.

    void readCustomProperties( const QDomNode &layerNode, const QString &keyStartsWith = QString() );
%Docstring
 Read custom properties from project file.
\param layerNode note to read from
\param keyStartsWith reads only properties starting with the specified string (or all if the string is empty)*
%End

    void writeCustomProperties( QDomNode &layerNode, QDomDocument &doc ) const;
%Docstring
Write custom properties to project file.
%End

    void readStyleManager( const QDomNode &layerNode );
%Docstring
Read style manager's configuration (if any). To be called by subclasses.
%End
    void writeStyleManager( QDomNode &layerNode, QDomDocument &doc ) const;
%Docstring
Write style manager's configuration (if exists). To be called by subclasses.

%Docstring
Add error message
