The type_index class wraps a pointer to type_info Class to assist in indexing by such objects.
class type_index {
public:
type_index(const type_info& tinfo);
const char *name() const;
size_t hash_code() const;
bool operator==(const type_info& right) const;
bool operator!=(const type_info& right) const;
bool operator<(const type_info& right) const;
bool operator<=(const type_info& right) const;
bool operator>(const type_info& right) const;
bool operator>=(const type_info& right) const;
};
The constructor initializes ptr to &tinfo.
name returns ptr->name().
hash_code returns ptr->hash_code().
operator== returns *ptr == right.ptr.
operator!= returns !(*this == right).
operator< returns *ptr->before(*right.ptr).
operator<= returns !(right < *this).
operator>returns right < *this.
operator>= returns !(*this < right).
