Question

I have a list<string> myList as a private attribute of my class. The content of this list is known at compile time and is constant. Is there any compact way (in C++03) to initialize its value? I can only think of this:

MyClass::MyClass(){
myList.push_back(string("str1"));
myList.push_back(string("str2"));
myList.push_back(string("str3"));
etc.
}

I would like something like this:

MyClass::MyClass():list("str1","str2","str3",etc.){
}

This code is not fully tested, but I would suggest this if you can’t use the new and cool stuff in C++11:

class MyClassCreator
{
    MyClass result;
public:
    MyClassCreator(std::string param)
    {
        result.myList.push_back(param);
    }

    MyClassCreator& operator()(std::string param)
    {
        result.myList.push_back(param); 
        return *this;
    }

    operator MyClass() { return result; }

};

Usage:

MyClass c = MyClassCreator("object1")("object2")("object3");
