``function_output_iterator`` requirements
|
|
.........................................
|
|
|
|
``UnaryFunction`` must be Assignable and Copy Constructible.
|
|
|
|
|
|
|
|
``function_output_iterator`` models
|
|
...................................
|
|
|
|
``function_output_iterator`` is a model of the Writable and
|
|
Incrementable Iterator concepts.
|
|
|
|
|
|
|
|
``function_output_iterator`` operations
|
|
.......................................
|
|
|
|
``explicit function_output_iterator(const UnaryFunction& f = UnaryFunction());``
|
|
|
|
:Effects: Constructs an instance of ``function_output_iterator``
|
|
with ``m_f`` constructed from ``f``.
|
|
|
|
|
|
``operator*();``
|
|
|
|
:Returns: An object ``r`` of unspecified type such that ``r = t``
|
|
is equivalent to ``m_f(t)`` for all ``t``.
|
|
|
|
|
|
``function_output_iterator& operator++();``
|
|
|
|
:Returns: ``*this``
|
|
|
|
|
|
``function_output_iterator& operator++(int);``
|
|
|
|
:Returns: ``*this``
|
