to encapsulate the logic (algorithm) into a class and take a combination (delegate) approach to solve the problem.To implement an abstract interface, inheritance is a way: we declare an abstract interface in a base class and place specific implementations in a specific subclass. A combination (delegate) is another way: we place the implementation of the interface in the combined object, placing the abstract interface in the composition class.3. completed strategy mode by Std:functionthroughstd

"Classical Strategy Mode"Traditional strategy practice will make fun into a separate virtual function in the inheritance system, namely:class fun{public: virtualvoid fun (int num) {...} ...

Provides Lightweight alternatives for dropshadowbitmapeffect in WPF Zhou yinhui WPF has an exciting new feature: We can easily provide bitmapeffect for visual elements, such as shadows. however, it is frustrating that bitmap results consume a lot of CPU resources. From the usual development, we can come up with two experiences: 1. Use bitmap effects as little as possible, because it is calculated by the CPU rather than the GPU. 2. Do not use bitmap

The alternative scheme of virtual function includes NVI technique and strategy design mode. The NVI technique itself is a special form of template method design mode.One drawback of moving functions from member functions to class external functions is that non-member functions cannot access the Non-public members of class.The Tr1::function object behaves like a generic function pointer. Such an object can accept all the callable objects (callable entities) that are compatible with the given targ

Use jquery's OnLoad method to load the page, but after this method jumps to multiple pages, clicking back Forward on the top of the browser is not valid, but you can think of adding a back button. So the more popular is this approach: Take a look at the code example description for the frameset tag: The code above works as follows: These are the alternatives to the HTML5 f

Brief description: It was originally compiled and installed. Because there are too many library files associated during the compilation process, the installation files must be sequential and there are too many errors. When rrdtool is started, it says that everything cannot be installed, due to time issues, I chose yum for installation. for compilation and installation, this is much simpler. She automatically installed all the associated files, saving a lot of trouble, the following describes how

Install Cacti on CentOS7 Cacti is an excellent open-source monitoring software that is implemented in php. It uses the snmp service to obtain data and then uses rrdtool to store and update data. When users view data, rrdtool generates charts and presents them to users. After CentOS7, the default database is MariaDB, which is a branch of MySQL and stores variables and calls them. The MariaDB database does no
