- [section boost/python/dict.hpp]
- [section Introduction]
- Exposes a [link concepts.objectwrapper.typewrapper_concept_requirements TypeWrapper] for the Python [@http://www.python.org/dev/doc/devel/lib/typesmapping.html `dict`] type.
- [endsect]
- [section Class `dict`]
- Exposes the [@http://www.python.org/dev/doc/devel/lib/typesmapping.html mapping protocol] of Python's built-in `dict` 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 `dict` is publicly derived from [link object_wrappers.boost_python_object_hpp.class_object `object`], the public `object` interface applies to `dict` instances as well.
