5.1 ZODB.PersistentMapping

The PersistentMapping class is a wrapper for mapping objects that will set the dirty bit when the mapping is modified by setting or deleting a key.

PersistentMapping(container = {})
Create a PersistentMapping object that wraps the mapping object container. If you don't specify a value for container, a regular Python dictionary is used.

PersistentMapping objects support all the same methods as Python dictionaries do.
