object Memoize

Memoize supplies a number of functions for generating memoized versions of Scala's functions using a MutableCache instance.

For example,

import com.twitter.storehaus.cache._

scala> val sleepyToString = Memoize(MapCache.empty[Int, String].toMutable()) { i => println("CALCULATING!"); i.toString }
sleepyToString: com.twitter.storehaus.cache.Memoize22[Int,String] = <function22>

scala> sleepyToString(10)
CALCULATING!
res21: String = 10

scala> sleepyToString(10)
res22: String = 10

// Get the backing function back out with backingFn:

scala> sleepyToString.backingFn(10)
CALCULATING!
res23: String = 10
