class BloomFilter[T] extends (T) ⇒ Boolean with Serializable

A BloomFilter is an approximate set that sometimes gives false positives. That is, if bf(x) returns true, then it might have been added to the set. If it returns false, then it definitely has not. This is useful for caching and approximation.
