  extended by 
org.eclipse.gmf.runtime.diagram.ui.resources.editor.document.DocumentProviderRegistry

public class DocumentProviderRegistry
extends java.lang.Object

A name extension rule always overrules an editor input type rule. Editor input type rules follow the same rules IAdapterManager used to find object adapters.
