back_insert_iterator Class
Describes an iterator adaptor that satisfies the requirements of an output iterator. It inserts, rather than overwrites, elements into the back end of a sequence and thus provides semantics that are different from the overwrite semantics provided by the iterators of the C++ sequence containers. The back_insert_iterator class is templatized on the type of container.
For a list of all members of this type, see back_insert_iterator Members.
template <class Container>
class back_insert_iterator
Parameters
- Container
The type of container into the back of which elements are to be inserted by a back_insert_iterator.
Remarks
The container must satisfy the requirements for a back insertion sequence where is it possible to insert elements at the end of the sequence in amortized constant time. STL sequence containers defined by the deque Class, list Class and vector Class provide the needed push_back member function and satisfy these requirements. These three containers as well as strings may each be adapted to use with back_insert_iterators. A back_insert_iterator must always be initialized with its container.
