Inside a CommandFn function, use opt.GetRequiredArg to get the argument value and remove it from the remaining arguments. There are also GetRequiredArgInt and GetRequiredArgFloat64 variants. These functions automatically print an error message if the argument is not found or if the type cast fa...

在传统面向对象语言C++/Java里面我们经常会写类似函数,它使用一个父类指针作为参数,然后带使用的时候,可以传入父类的实例,或者子类的实例,然后在函数内用动态类型检测,比如dynamic_cast,来觉得传入的是父类还是子类。 还是以前面例子来说:C++版本: #include<stdio.h>classA{public:virtualvoidHello(){printf("in ...

出现这种问题的情况下,首先,你肯定进行了数据的转换,不管是convert还是cast 一定是用了其中的一种方式,其次,如果转换前的数据中含有非数字字符,例如abc >;%特殊字符,你心里也有数,这个转换肯定是不行的,而我出现这个问题的时候比较特殊,这个字段本应该是纯数字,数据量不多,大概3000+条数据,但是其中有一条数据是有...
