引子 在现实编码过程中，曾经遇到过这样的问题“warning:’Base’ has no out-of-line method definition; its vtable will be emitted in every translation unit”。由于对这个warning感兴趣，于是搜集了相关资料来解释这个warning相关的含义。 C++虚表内部架构 Vague Linkage out-of-line virtual method C++虚表内部架构 在C++实现机制RTTI中，我们大概谈到过C++虚表的组织结构。 但是我们对C++虚表的详细实现细节并没有具体谈及，例如在继承体系下虚表的组织以及在多重继承下虚表的组织方式。 （1）没有继承情况下的类虚表结构 #include <iostream> using namespace std; class Base { public: virtual void Add() { cout << "Base Virtual Add()!"<< "\n"; } virtual void Sub() { cout << "Base Virtual Sub()!" << "\n"; } virtual void Div() { cout << "Base Virtual Div()!" << "\n"; } }; int main()

When the user clicks, it will open a second drawerlayout like this below. The user can get back to the first by clicking on the arrow Main Menu . Is this possible? Many thanks for any suggestions 回答1: It's unclear how exactly you wish to implement your drawer UI, so the following solution is rather generic, in that it should work with NavigationView s, RecyclerView s, or pretty much whatever type of View s you'd like.

With jQuery you can just listen after a click event on a specific type of element like a <li> and add a class to its child element for a menu to open. I'm trying to do the same thing like the menu on this page http://geedmo.com/themeforest/wintermin/dashboard.html , with Angular. But can't find the correct way by using my own directive or existing ones like ng-hide and ng-show. If anyone have an example og guides on how to do this

How? 回答1: To detect if the request is a master or not requires the use of the RequestStack , which should be injected into your controller. The request stack has 3 useful methods getCurrentRequest (); getMasterRequest (); getParentRequest (); The getParentRequest() will always return null if the current request is the master. 回答2: I was looking for this myself, and it seems it is just passed around, so there doesn't seem to be one single place that knows what it is.

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I have a table lets call it table1, and the data in two of the columns has been destroyed. Fortunately I have an old backup of the table. In the old backup the values for the two columns in question are correct but the rest of the columns are outdated so I can't simply import the whole dump. So instead I've imported it into another table which I'll call table2. Each record has an id which is the same in both tables. So basically I need a query that will go through each record in table1 and update column1 and column2 with the corresponding
