type_index Class

 

The latest version of this topic can be found at 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).
