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

Expression	Semantics
`back_inserter<s>`	An Inserter `in`, equivalent to struct in : inserter<s,push_back<_1,_2> > {};

back_inserter<s>

An Inserter in, equivalent to

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> > ));
