#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 std::variant<T...> and std::optional<std::variant<T...> >, where T... must be a subset of the parameters of V. Should the std::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. |
