class Memoization[I, K, O] extends (I) ⇒ O

Represents a generic form of memoization. Modified from Pathikrit Bhowmick's copy of Scala Memoization.

I

Represents the input to the memoized function

K

Represents the type of key to use for cached results

O

Represents the output of the memoized function

  1. new Memoization(memoFunc: (I) ⇒ O, cacheInvalidFunc: (K) ⇒ Boolean = (_: K) => false, cache: Map[K, O] = MutableMap.empty[K, O])(implicit convertToKey: (I) ⇒ K)

    memoFunc

    Represents the function that will be memoized

    cacheInvalidFunc

    Represents a function that, if it yields true, will mark the current cache element represented by K as invalid and rerun the memo function

    cache

    The map used to store the cache of results to be fed back as a result of memoization
