Derived classes inherit the member functions of the templated base class, which are not accessible by default, and are named for the templated base class. The reason is that the customization of the template may cancel some functions, so that they cannot be accessed by default in order to detect errors at compile time. Derived classes access templated base classes, including three methods: 1. When callin

Internal classes that use static adornments are called static inner classes, but we prefer to call them nested inner classes . There is one big difference between static inner and non-static inner classes, and we know that a non-static inner class implicitly holds a reference after compilation, which points to the perimeter in which it was created, but does not have a static inner class. Without this refere

Because some frameworks are designed to often see Db::get (' Mall ')->where (' AAA '); Why can't you do this? Db::get (' Mall '):: Where (' aaa '); Other problems are that objects produced through a factory or a static container are generally cost-static.For example, a log class, I have seen static also seen in the non-static design. A little choice. Don't tell me what type of tool is best static, no new crap. Reply content: Because some framewor
