values.
:class:`.NamespaceManager` provides a dictionary-like interface,
implementing ``__getitem__()``, ``__setitem__()``, and
``__contains__()``, as well as functions related to lock
acquisition.
The implementation for setting and retrieving the namespace data is
handled by subclasses.
NamespaceManager may be used alone, or may be accessed by
one or more :class:`.Value` objects. :class:`.Value` objects provide per-key
services like expiration times and automatic recreation of values.
Multiple NamespaceManagers created with a particular name will all
share access to the same underlying datasource and will attempt to
synchronize against a common mutex object. The scope of this
sharing may be within a single process or across multiple
processes, depending on the type of NamespaceManager used.
The NamespaceManager itself is generally threadsafe, except in the
case of the DBMNamespaceManager in conjunction with the gdbm dbm
implementation.

multiple threads or processes which wish to generate a new
cache value.
This function is typically an instance of
:class:`.FileSynchronizer`, :class:`.ConditionSynchronizer`,
or :class:`.null_synchronizer`.
The creation lock is only used when a requested value
does not exist, or has been expired, and is only used
by the :class:`.Value` key-management object in conjunction
with a "createfunc" value-creation function.

:meth:`.NamespaceManager.remove` method.

A return value of ``True`` indicates the lock has
been acquired.
By default the function returns ``True`` unconditionally.
'replace' is a hint indicating the full contents
of the namespace may be safely discarded. Some backends
may implement this (i.e. file backend won't unpickle the
current contents).

dd� Z dS )�AbstractDictionaryNSManagera� A subclassable NamespaceManager that places data in a dictionary.
Subclasses should provide a "dictionary" attribute or descriptor
which returns a dict-like object. The dictionary will store keys
that are local to the "namespace" attribute of this manager, so
ensure that the dictionary will not be used by any other namespace.
e.g.::
import collections
cached_data = collections.defaultdict(dict)
class MyDictionaryManager(AbstractDictionaryNSManager):
def __init__(self, namespace):
AbstractDictionaryNSManager.__init__(self, namespace)
self.dictionary = cached_data[self.namespace]
The above stores data in a global dictionary called "cached_data",
which is structured as a dictionary of dictionaries, keyed
first on namespace name to a sub-dictionary, then on actual
cache key to value.
