Explain this C++ operator definition
- by David Johnstone
I have the following operator defined in a C++ class called StringProxy:
operator std::string&()
{
return m_string;
}
a) What is this and how does this work? I understand the idea of operator overloading, but they normally look like X operator+(double i).
b) Given an instance of StringProxy, how can I use this operator to get the m_string?
