Tools: Caching

Decorators for memoization/caching.

tad_mctc.tools.caching.memoize(fcn)

Memoization decorator that writes the cache to the object itself, hence not allowing the specification of __slots__. It works with and without function arguments.

Note that lru_cache can produce memory leaks for a method.

Parameters:

fcn (Callable[[Any], T]) – Function to memoize

Returns:

Memoized function.

Return type:

Callable[[Any], T]

tad_mctc.tools.caching.memoize_all_instances(fcn)

Memoization with shared cache among all instances of the decorated function. This decorator allows specification of __slots__. It works with and without function arguments.

Note that lru_cache can produce memory leaks for a method.

Parameters:

fcn (Callable[[Any], T]) – Function to memoize

Returns:

Memoized function.

Return type:

Callable[[Any], T]
