- [section boost/python/tuple.hpp]
- [section Introduction]
- Exposes a [link concepts.objectwrapper.typewrapper_concept_requirements TypeWrapper] for the Python [@http://www.python.org/doc/current/tut/node7.html#SECTION007300000000000000000`tuple`] type.
- [endsect]
- [section Class `tuple`]
- Exposes the interface of Python's built-in tuple type. The semantics of the constructors and member functions defined below can be fully understood by reading the [link concepts.objectwrapper.typewrapper_concept_requirements TypeWrapper] concept definition. Since tuple is publicly derived from [link object_wrappers.boost_python_object_hpp.class_object `object`], the public `object` interface applies to `tuple` instances as well.
