KeyedCache

class KeyedCache[K, T] extends AnyRef

A simple Read-through cache.

An example of using it with a ProtoUser subclass:

object UserCache extends KeyedCache[Long, User](100, Full(0.75f), (id: Long) => User.find(By(User.id, id)))

Instance Constructors

  1. new KeyedCache(size: Int, loadFactor: Box[Float], cons: (K) ⇒ Box[T])

    size

    the size of the cache

    loadFactor

    the optional Load Factor

    cons

    A function that will take a value of type K and return a Box[T] populated into the cache if the return value is Full.
