What is the meaning of the following?

inline const char * operator*(AnEnumClass aclassinstance) {
    ...
}

Is it a function call operator overloading of the '*' operator or of the '()' operator? What does it accomplish and what is it used for?

CodePudding user response：

It's an overload of the * operator that is returning a const char *.

CodePudding user response：

inline  // function should be marked as inline.
const char *  // function returns this
operator *  // function is the multiplication operator
(AnEnumClass aClassInstance)  // RHS argument to operator

The operator takes as LHS whatever the encapsulating class is.

You invoke it with:

const char * aString = aClass * aEnum;

(Given instances of the encapsulating class and the enumeration type.)

Both Wikipedia and cppreference.com have a whole page on operator precedence and argumentation that you should peruse.
