golang monitoring

Conclusion:golang不支持解析string然后执行。golang的反射机制只能存在于已经存在的对象上面。It is not known whether the subsequent versions are planned, and now only the registration can be loaded, and then a reflection similar to the Java Factory pattern is implemented.code example: T: = reflect. ValueOf (human{}). Type () // H: = reflect. New (t). Elem () // New return address pointer h: = reflect. New (t). Interface () FMT. Println (h) hh:= H. (*Human) FMT

Is the method the call-to-power

Golang basics and golang Basics1. Inheritance overload is not supported. For example, for C ++ Java interfaces, modification of interfaces will affect the modification of class behavior of the entire interface to be modified. Go designers think this feature may be useless. 2. Any function definition must be followed by curly brackets after the function declaration and cannot be wrapped in a line break such

the original code when expanding the function. Regardless of the software refactoring level, when the new recruits take over the boss's code, I think the most headache is to increase demand, because you do not know what to change the code to bring a hidden BUG.We always ideal can use the "plug-in" thinking to adapt to demand, write a good framework, and then classify, each of the abstract role is a large container, and then each time to the container plug into a plug-in, to a demand, do a plug-

[TOC] "Recorded in February 2018" The concept of reflection in programming languages In computer science, reflection refers to a class of applications that are self-describing and self-controlling. In other words, this kind of application uses some mechanism to realize the description (self-representation) and monitoring (examination) of its own behavior, and can adjust
