#include <CGAL/iterator.h>

Inherits from

O.

Definition

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

Template Parameters
Vmust be a std::tuple<...> of the types of values to be accepted and dispatched.
Omust be a std::tuple<...> of the types of corresponding output iterators.
Is Model Of:
OutputIterator
