NOTE: This is a hack
|
|
if f args are like (a, b1, b2, b3) and returns [o1, o2, o3] where
|
|
o1, o2, o3 are output of f respectively for (a, b1), (a, b2) and
|
|
(a, b3) then we memoize f(a, b1, b2, b3)'s result but also
|
|
f(a, b1) => o1 , f(a, b2) => o2 and f(a, b3) => o3.
|
|
Example:
|
|
|
|
>>> partialsum = lambda a, *b: [a + bn for bn in b]
|
|
>>> partialsum = memoize(partialsum)
|
|
|
|
Create a class that wraps the integer '3', otherwise we cannot add
|
|
_phabstatuscache to it for the test
|
|
>>> class IntWrapperClass(int):
|
|
... def __new__(cls, *args, **kwargs):
|
|
... return super(IntWrapperClass, cls).__new__(cls, 3)
|
|
|
|
>>> three = IntWrapperClass()
|
|
>>> partialsum(three, 1, 2, 3)
|
|
[4, 5, 6]
|
|
|
|
As expected, we have 4 entries in the cache for a call like f(a, b, c, d)
|
|
>>> pp(three._phabstatuscache)
|
|
{(3, 1): [4], (3, 1, 2, 3): [4, 5, 6], (3, 2): [5], (3, 3): [6]}
