Bug 12144 Re-format all files [code manipulation]
I could be nice to have the ability to re-format all Java files in one time. Beyond, to do all java file based actions on a selection of files (as for search for example).
org.eclipse.jdt.ui/ui/org/eclipse/jdt/ui/actions/GenerateActionGroup.java
fGenerateConstructorUsingFields.update(selection);
		fAddJavaDocStub.update(selection);
		fAddToClasspathAction.update(selection);
		fRemoveFromClasspathAction.update(selection);
		fExternalizeStrings.update(selection);
		fFindStringsToExternalize.update(selection);
		fAddTaskAction.update(selection);
		fOrganizeImports.update(selection);
		fSortMembers.update(selection);
		if (selection instanceof IStructuredSelection) {
			IStructuredSelection ss= (IStructuredSelection)selection;
			fAddBookmark.selectionChanged(ss);
		} else {
			fAddBookmark.setEnabled(false);
		}
		
		registerSelectionListener(provider, fOverrideMethods);
		registerSelectionListener(provider, fAddGetterSetter);
		registerSelectionListener(provider, fAddDelegateMethods);
		registerSelectionListener(provider, fAddUnimplementedConstructors);
		registerSelectionListener(provider, fGenerateConstructorUsingFields);
		registerSelectionListener(provider, fAddJavaDocStub);
		registerSelectionListener(provider, fAddBookmark);
		registerSelectionListener(provider, fAddToClasspathAction);
		registerSelectionListener(provider, fRemoveFromClasspathAction);
		registerSelectionListener(provider, fExternalizeStrings);
		registerSelectionListener(provider, fFindStringsToExternalize);
		registerSelectionListener(provider, fOrganizeImports);
		registerSelectionListener(provider, fSortMembers);
		registerSelectionListener(provider, fAddTaskAction);
