Between runs of Planet we need somewhere to store the feed information we parsed, this is so we don't lose information when a particular feed goes away or is too short to hold enough items. This module provides the code to handle this cache transparently enough that the rest of the code can take the persistance for granted.

This class is designed to hold information that is stored in a cache between instances. It can act both as a dictionary (c['foo']) and as an object (c.foo) to get and set values and supports both string and date values. If you wish to support special fields you can derive a class off this and implement get_FIELD and set_FIELD functions which will be automatically called. tstringtdatetnullicCsFh|_h|_h|_||_|iddƒ|_||_ dS(Nt s%20( tselft_typet_valuet_cachedtcachet_cachetid_treplacet_idtroott_root(RR R R((tC/home/users/jdub/public_html/bzr/planet/devel/trunk/planet/cache.pyt__init__(s     cCs7|iddƒ}|io|Sn|id|SdS(s,Return the cache key name for the given key.Rt_N(tkeyR RRR (RR((Rt cache_key1s  cCsÑ|io d}n |i}|ii|ƒo|i|idƒ}ndSx||D]t}|i |ƒ}|i i|ƒ p|i |o=|i||i |<|i|d|i |RR@t __contains__t __setitem__t __getitem__t __delitem__t __delattr__RCRD(((RRs:               cCs[tid|ƒ}tid|ƒ}tid|ƒ}tid|ƒ}tii||ƒS(s•Return a filename suitable for the cache.
