上面的BIONIC_DISALLOW_IMPLICIT_CONSTRUCTORS(__locale_t);其实是禁止隐式构造的宏,如下: 将类的默认构造函数,拷贝构造函数,赋值重载都隐藏起来 #define DISALLOW_COPY_AND_ASSIGN(TypeName) \ private: \ TypeName(const TypeName&); \ TypeName& operator=(const TypeName&)#define DISALLOW_IMPLIC...

Define this macro to 1 to make not_null<>'s constructor explicit. Default is 0. Note that in Microsoft's GSL the constructor is explicit. For implicit construction you can also use the gsl-lite-specific not_null<>-derived class not_null_ic<>. gsl_CONFIG_TRANSPARENT_NOT_NULL=0 Define ...

-implicit:[class, none] Controls the generation of class files for implicitly loaded source files. To automatically generate class files, use-implicit:class. To suppress class file generation, use-implicit:none. If this option is not specified, then the default is to automatically generate class ...
了解隐式接口和编译期多态(class 和 templates 都支持接口(interfaces)和多态(polymorphism);class 的接口是以签名为中心的显式的(explicit),多态则是通过 virtual 函数发生于运行期;template 的接口是奠基于有效表达式的隐式的(implicit),多态则是通过 template 具现化和函数重载解析(function overloading resolution)发...
