type_index Class

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).
