- The zip iterator provides the ability to parallel-iterate
- over several controlled sequences simultaneously. A zip
- iterator is constructed from a tuple of iterators. Moving
- the zip iterator moves all the iterators in parallel.
- Dereferencing the zip iterator returns a tuple that contains
- the results of dereferencing the individual iterators.
- The tuple of iterators is now implemented in terms of a Boost fusion sequence.
- Because of this the 'tuple' may be any Boost fusion sequence and, for backwards
- compatibility through a Boost fusion sequence adapter, a Boost tuple. Because the
- 'tuple' may be any boost::fusion sequence the 'tuple' may also be any type for which a
- Boost fusion adapter exists. This includes, among others, a std::tuple and a std::pair.
- Just remember to include the appropriate Boost fusion adapter header files for these
- other Boost fusion adapters. The zip_iterator header file already includes the
- Boost fusion adapter header file for Boost tuple, so you need not include it yourself
- to use a Boost tuple as your 'tuple'.
