However it may have little benefit other than being consistent with the Java API. Once you have an IndexProducer you typically put all the indices into a Bloom filter. But you cannot construct a BloomFilter from an IndexProducer alone as you require the Shape. So at present I cannot see a common use case for the chaining methods (compose, apply) that come with the Function interface. Alex
