#include <CGAL/iterator.h>
O.
The class Dispatch_or_drop_output_iterator
defines an OutputIterator
that contains a tuple of output iterators, and dispatches among those based on the type of the value type which is put in it.
Besides defining assignment for all parameters of V
and for a tuple of type V
, it is also defined for the types boost::variant<T...>
and boost::optional<boost::variant<T...> >
, where T...
must be a subset of the parameters of V
. Should the boost::optional
be empty, it will be discarded.
Parameters
V | must be a std::tuple<...> of the types of values to be accepted and dispatched. |
O | must be a std::tuple<...> of the types of corresponding output iterators. |
