Classe type_index
A classe type_index encapsula um ponteiro para a Classe type_info para auxiliar na indexação por esses objetos.
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; };
O construtor inicializa ptr para &tinfo.
name retorna ptr->name().
hash_code retorna ptr->hash_code().
operator== retorna *ptr == right.ptr.
operator!= retorna !(*this == right).
operator< retorna *ptr->before(*right.ptr).
operator<= retorna !(right < *this).
operator> retorna right < *this.
operator>= retorna !(*this < right).
