The template class describes an output iterator object. It inserts elements into a container of type
Container, which it accesses via the protected pointer object it stores called container. The
container must define:
the member type const_reference, which is the type of a constant reference to an element
of the sequence controlled by the container
●
the member type reference, which is the type of a reference to an element of the sequence
controlled by the container
●
the member type value_type, which is the type of an element of the sequence controlled by
the container
●
the member function push_front(value_type val), which prepends a new element
with value val to the beginning of the sequence
●
front_insert_iterator::container_type
typedef Container container_type;
The type is a synonym for the template parameter Container.
front_insert_iterator::front_insert_iterator
explicit front_insert_iterator(Container& cont);
The constructor initializes container with &cont.
