inherited

This type represents a pointer-to-value_type.

Definition at line 136 of file stl_iterator_base_types.h.

◆ reference

template<typename _Category , typename _Tp , typename _Distance = ptrdiff_t, typename _Pointer = _Tp*, typename _Reference = _Tp&>
typedef _Reference std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::reference
inherited

typedef _Tp std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference >::value_type
inherited

The type "pointed to" by the iterator.
