The template class describes an output iterator object. It inserts elements into a container of type Cont
, which it
accesses via the protected reference object it stores called container
. The container must define:
value_type
, which is the type of an element of the sequence controlled by the container.push_back
(value_type c)
, which appends a new element with value c
to the end of the
sequence.
