Synopsis

template<
      typename Seq
    >
struct back_inserter
{
    // unspecified
    // ...
};

Description

Inserts elements at the end of the sequence.

Header

#include <boost/mpl/back_inserter.hpp>

Model of

Inserter

Parameters

Parameter Requirement Description
Seq Back Extensible Sequence A sequence to bind the inserter to.

Expression semantics

The semantics of an expression are defined only where they differ from, or are not defined in Inserter.

For any Back Extensible Sequence s:

Expression Semantics
back_inserter<s>

An Inserter in, equivalent to

struct in : inserter<s,push_back<_1,_2> > {};

Complexity

Amortized constant time.

Example

typedef copy<
      range_c<int,5,10>
    , back_inserter< vector_c<int,0,1,2,3,4> >
    >::type range;
   
BOOST_MPL_ASSERT(( equal< range, range_c<int,0,10> > ));
