What's the meaning of the following code?
abbreviated version from json.hpp:
template<typename T, std::size_t n>
reference operator[](T * (&key)[n])
{
return operator[](static_cast<const T>(key));
}
template<typename T>
reference operator[](T* key)
{
return m_value.object->operator[](key);
}and const_reference version of them.
Normally m_value.object is an std::map and key is an std::string. But the code must have been placed for a reason. I just want to know why.
