代码重构 & JDT编程实现全部代码修改撤销（包括重构且不弹出确认框）

		IUndoContext context= (IUndoContext)ResourcesPlugin.getWorkspace().getAdapter(IUndoContext.class);
		
		IWorkbenchPartSite workbenchpartSite = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor().getSite();
		
		
		
		IOperationHistory operationHistory = PlatformUI.getWorkbench().getOperationSupport().getOperationHistory();
	
		UndoActionHandler undoAction = new UndoActionHandler(workbenchpartSite, context);
		
		

		
		IUndoableOperation[] operations = operationHistory
				.getUndoHistory(IOperationHistory.GLOBAL_UNDO_CONTEXT);
		System.out.println("operations's length : "+operations.length);
		
		
		for(int i = operations.length - 1; i >= 0; i--)
			if(operations[i].canUndo())
				try 
					System.out.println("undo Label    : " + operations[i].getLabel());
					
					operationHistory.undoOperation(operations[i], null, undoAction);
				 catch (ExecutionException e) 
					// TODO Auto-generated catch block
					e.printStackTrace();
				
			
		

如果是重构的撤销，operations[i].getLabel()会输出  Extract Class 或者 Move Method等具体的重构操作名称。
