..class::BsdDbShelf(dict, protocol=None, writeback=False, keyencoding='utf-8')

A subclass of:class:`Shelf` which exposes:meth:`first`,:meth:`!next`,

:meth:`previous`,:meth:`last` and:meth:`set_location` which are available

in the third-party:mod:`bsddb` module from `pybsddb

A subclass of:class:`Shelf` which exposes:meth:`!first`,:meth:`!next`,

:meth:`!previous`,:meth:`!last` and:meth:`!set_location` methods.

These are available

in the third-party:mod:`!bsddb` module from `pybsddb

<https://www.jcea.es/programacion/pybsddb.htm>`_ but not in other database

modules. The *dict* object passed to the constructor must support those

methods. This is generally accomplished by calling one of

:func:`bsddb.hashopen`,:func:`bsddb.btopen` or:func:`bsddb.rnopen`. The

:func:`!bsddb.hashopen`,:func:`!bsddb.btopen` or:func:`!bsddb.rnopen`. The

optional *protocol*, *writeback*, and *keyencoding* parameters have the same

interpretation as for the:class:`Shelf` class.
