Submodules¶
-
temporalcache.expire.daily(on=0, tz=None, maxsize=128, persistent='', custom=None, **kwargs)[source]¶
-
temporalcache.expire.expire(second=None, minute=None, hour=None, day=None, day_of_week=None, week=None, month=None, tz=None, maxsize=128, persistent='', custom=None, **kwargs)[source]¶ Expires all entries in the cache @ whole number time
for example, @expire(0, 30, 16) will expire the cache at 4:30pm every day
-
temporalcache.expire.hourly(on=0, tz=None, maxsize=128, persistent='', custom=None, **kwargs)[source]¶
-
temporalcache.expire.minutely(on=0, tz=None, maxsize=128, persistent='', custom=None, **kwargs)[source]¶
-
temporalcache.expire.monthly(on=0, tz=None, maxsize=128, persistent='', custom=None, **kwargs)[source]¶
-
temporalcache.interval.interval(seconds=0, minutes=0, hours=0, days=0, weeks=0, months=0, years=0, maxsize=128, persistent='', custom=None, **kwargs)[source]¶ Expires all entries in the cache every interval

temporalcache.persistent_lru_cache.persistent_lru_cache(filename, save_every=1, maxsize=128, typed=False)[source]¶ Least-recently-used cache decorator.
filename is a path to a pickle file that will store the cache between runs.
If save_every is set to None, the cache will only be saved at exit (or when wrapper.cache_save is explicitly callde). If it’s a number N, the cache will be saved every N cache misses.
If maxsize is set to None, the LRU features are disabled and the cache can grow without bound.
If typed is True, arguments of different types will be cached separately. For example, f(3.0) and f(3) will be treated as distinct calls with distinct results.
Arguments to the cached function must be hashable.
View the cache statistics named tuple (hits, misses, maxsize, currsize) with f.cache_info(). Clear the cache and statistics with f.cache_clear(). Access the underlying function with f.__wrapped__.
