Synopsis

template<
      typename Iterator
    >
struct next
{
    typedef |unspecified| type;
};

Description

Returns the next iterator in the sequence. |Note:| next has a number of overloaded meanings, depending on the type of its argument. For instance, if X is an |Integral Constant|, next<X> returns an incremented |Integral Constant| of the same type. The following specification is iterator-specific. Please refer to the corresponding concept's documentation for the details of the alternative semantics |-- end note|.

Header

#include <boost/mpl/next_prior.hpp>

Parameters

Expression semantics

For any |Forward Iterator|s iter:

typedef next<iter>::type j;

typedef iter::next j;

Complexity

Amortized constant time.

Example

typedef vector_c<int,1> v;
typedef begin<v>::type first;
typedef end<v>::type last;
BOOST_MPL_ASSERT(( is_same< next<first>::type, last > ));
