[news.eclipse.modeling.gmf] How to integrate "DiagramActionBarContributo

[jiezi <jiezi506@xxxxxxxxx>]

I need to integrate my XXXDiagramEditor into XXMultiPageEditor, but the 
question was  How to integrate "DiagramActionBarContributor" into 
"MultiPageEditorActionBarContributor"

The XXXDiagramActionBarContributor had only two method:

public class XXXDiagramActionBarContributor extends
		DiagramActionBarContributor {

	/**
	 * @generated
	 */
	protected Class getEditorClass() {
		return Xpdl2DiagramEditor.class;
	}

	/**
	 * @generated
	 */
	protected String getEditorId() {
		return Xpdl2DiagramEditor.ID;
	}
}
