---------

The time delta afterwhich a cached result is considered stale. Calls
made after the result goes stale will trigger a recalculation of the

determined by the optional next_time argument.

False.
pickle_reload (optional) : bool
If set to True, in-memory cache will be reloaded on each cache read,
enabling different threads to share cache. Should be set to False for
faster reads in single-thread programs. Defaults to True.
mongetter (optional) : callable
A callable that takes no arguments and returns a pymongo.Collection

The positional and keyword arguments to the wrapped function must be
hashable (i.e. Python's immutable built-in objects, not mutable
containers). Also, notice that since objects which are instances of
user-defined classes are hashable but all compare unequal (their hash
value is their id), equal objects across different sessions will not yield
identical keys.
Arguments
---------
stale_after (optional) : datetime.timedelta
The time delta afterwhich a cached result is considered stale. Calls
made after the result goes stale will trigger a recalculation of the
result, but whether a stale or fresh result will be returned is
determined by the optional next_time argument.
next_time (optional) : bool
If set to True, a stale result will be returned when finding one, not
waiting for the calculation of the fresh result to return. Defaults to
False.
pickle_reload (optional) : bool
If set to True, in-memory cache will be reloaded on each cache read,
enabling different threads to share cache. Should be set to False for
faster reads in single-thread programs. Defaults to True.
mongetter (optional) : callable
A callable that takes no arguments and returns a pymongo.Collection
object with writing permissions. If unset a local pickle cache is used
instead. | entailment |
