SerialView is a Python mapping view which serializes all key-value pairs before storing them in the given mapping object. The general use case is to use this class to wrap around a bsddb.DB or a LiteMap object (which only take string keys/values).
The provided SerialView classes uses repr for the keys and pickle for the values. One can easily change the serialization method by extending the class and overriding the _(load|dump)_(key|value) methods.
Example:
import bsddb
from serialview import SerialView
db = bsddb.hashopen('path_to_db')
view = SerialView(db)
view['key'] = ('complex value', 1, 2, (3, 4))
print view['key']
# ('complex value', 1, 2, (3, 4))
