Public Functions

prepared(const derived_type &data)¶

prepared(const prepared<T, true> &other)¶: a visitor keeps a reference to the index, So while copy constructing if the other object is going to be destructed then the copied visitor will have a dangling reference to the other._index hence the copy constructor instantiates a visitor again from the copied index
