class documentation

class LocalWeakReferencedCache(weakref.WeakKeyDictionary):

View In Hierarchy

A weakref.WeakKeyDictionary implementation that uses LocalCache as its underlying data structure, making it ordered and capable of being size-limited.

Useful for memoization, while avoiding keeping received arguments in memory only because of the cached references.

Note: like LocalCache and unlike weakref.WeakKeyDictionary, it cannot be instantiated with an initial dictionary.
