See L{memcache} for an overview. In all cases where a key is used, the key can be either: 1. A simple hashable type (string, integer, etc.). 2. A tuple of C{(hashvalue, key)}. This is useful if you want to avoid making this module calculate a hash value. You may prefer, for example, to keep all of a given user's objects on the same memcache server, so you could use the user's unique id as the hash value. @group Setup: __init__, set_servers, forget_dead_hosts, disconnect_all, debuglog @group Insertion: set, add, replace, set_multi @group Retrieval: get, get_multi @group Integers: incr, decr @group Removal: delete, delete_multi @sort: __init__, set_servers, forget_dead_hosts, disconnect_all, debuglog, set, set_multi, add, replace, get, get_multi, incr, decr, delete, delete_multi i i i i i t MemcachedKeyErrorc B s e Z RS( ( R R ( ( ( s/ /opt/cpanel-ccs/twistedcaldav/memcacheclient.pyR( � s t MemcachedKeyLengthErrorc B s e Z RS( ( R R ( ( ( s/ /opt/cpanel-ccs/twistedcaldav/memcacheclient.pyR) � s t MemcachedKeyCharacterErrorc B s e Z RS( ( R R ( ( ( s/ /opt/cpanel-ccs/twistedcaldav/memcacheclient.pyR* � s t MemcachedKeyNoneErrorc B s e Z RS( ( R R ( ( ( s/ /opt/cpanel-ccs/twistedcaldav/memcacheclient.pyR+ � s t MemcachedKeyTypeErrorc B s e Z RS( ( R R ( ( ( s/ /opt/cpanel-ccs/twistedcaldav/memcacheclient.pyR, � s t MemcachedStringEncodingErrorc B s e Z RS( ( R R ( ( ( s/ /opt/cpanel-ccs/twistedcaldav/memcacheclient.pyR- � s c C s� t j | � | j | � | | _ i | _ | | _ | | _ | | _ | | _ | | _ t � } y% | j | d | j �} t | _ Wn t k r� t | _ n Xd S( s Create a new Client object with the given list of servers. @param servers: C{servers} is passed to L{set_servers}. @param debug: whether to display error messages when a server can't be contacted. @param pickleProtocol: number to mandate protocol used by (c)Pickle. @param pickler: optional override of default Pickler to allow subclassing. @param unpickler: optional override of default Unpickler to allow subclassing. @param pload: optional persistent_load function to call on pickle loading.

Such as your db pri key fields. They're rotored through str() before being passed off to memcache, with or without the use of a key_prefix. In this mode, the key_prefix could be a table name, and the key itself a db primary key number. >>> mc.set_multi({42: 'douglass adams', 46 : 'and 2 just ahead of me'}, key_prefix='numkeys_') == [] 1 >>> mc.get_multi([46, 42], key_prefix='numkeys_') == {42: 'douglass adams', 46 : 'and 2 just ahead of me'} 1 This method is recommended over regular L{get} as it lowers the number of total packets flying around your network, reducing total latency, since your app doesn't have to wait for each round-trip of L{get} before sending the next one. See also L{set_multi}. @param keys: An array of keys. @param key_prefix: A string to prefix each key when we communicate with memcache. Facilitates pseudo-namespaces within memcache. Returned dictionary keys will not have this prefix. @return: A dictionary of key/value pairs that were available.
