Synopsis

template<
      typename X
    >
struct[end](./end.html){
    typedef_unspecified_type;
};

Description

Returns the sequence's past-the-end iterator. If the argument is not a Forward Sequence, returns void_.

Header

#include <[boost/mpl/begin\_end.hpp](../../../../boost/mpl/begin_end.hpp)>

Model of

Tag Dispatched Metafunction

Parameters

Expression semantics

For any arbitrary type x:

typedef[end](./end.html)<x>::type last;

| Return type: | Forward Iterator or void_. | | Semantics: | If x is Forward Sequence, last is an iterator pointing one past the last element in s; otherwise last is void_. | | Postcondition: | If last is an iterator, it is past-the-end. |

Complexity

Amortized constant time.

Example

typedef[vector](./vector.html)<long> v;
typedef[begin](./begin.html)<v>::type first;
typedef[end](./end.html)<v>::type last;[BOOST\_MPL\_ASSERT](./assert.html)(( is_same<[next](./next.html)<first>::type, last > ));
