Package pyxmpp :: Module expdict :: Class ExpiringDictionary |
|
object
--+ |dict
--+ | ExpiringDictionary
An extension to standard Python dictionary objects which implements item expiration. Each item in ExpiringDictionary has its expiration time assigned, after which the item is removed from the mapping. :Ivariables: - `_timeouts`: a dictionary with timeout values and timeout callback for stored objects. - `_default_timeout`: the default timeout value (in seconds from now). - `_lock`: access synchronization lock. :Types: - `_timeouts`: `dict` - `_default_timeout`: `int` - `_lock`: `threading.RLock`
Method Summary | |
---|---|
Initialize an `ExpiringDictionary` object. | |
__delitem__(self,
key)
| |
__getitem__(self,
key)
| |
__setitem__(self,
key,
value)
| |
Do the expiration of dictionary items. | |
Set item of the dictionary. | |

D.items() -> list of D's (key, value) pairs, as 2-tuples | |
D.iteritems() -> an iterator over the (key, value) items of D | |
D.iterkeys() -> an iterator over the keys of D | |
D.itervalues() -> an iterator over the values of D | |
D.keys() -> list of D's keys | |
If key is not found, d is returned if given, otherwise KeyError is raised | |
2-tuple; but raise KeyError if D is empty | |

__init__(self,
default_timeout=300)
|
expire(self)Do the expiration of dictionary items. Remove items that expired by now from the dictionary. |
set_item(self, key, value, timeout=None, timeout_callback=None)Set item of the dictionary. :Parameters: - `key`: the key. - `value`: the object to store. - `timeout`: timeout value for the object (in seconds from now). - `timeout_callback`: function to be called when the item expires. The callback should accept none, one (the key) or two (the key and the value) arguments. :Types: - `key`: any hashable value - `value`: any python object - `timeout`: `int` - `timeout_callback`: callable |
