Method Details

__getitem__(self, param)
(Indexing operator)

Return referenced object or association data.
Parameters:
param - Referenced object primary key value or application object.
Returns:
Referenced object or association data (depends on cache type). If data is not found then None or empty set is returned.
Overrides:
bazaar.cache.Cache.__getitem__

See Also: bazaar.cache.FullObject bazaar.cache.FullAssociation

getEmpty(self)

Get data which will be returned when object or association data will not be found in the cache.

Instance Variable Details

empty

Is returned by __getitem__ method when referenced object or association data are not found in cache.
