Iterator<int[]> ?

Or foolproof:

class IndexCount {
    final int index;
    final int count;
    // ...
}

Iterator<IndexCount>


The CountingBloomFilter already has a method forEachCount(…).

I was reluctant to add some sort of iterator:

Iterator<?> iterator()

But we could put in:

Iterator<IndexCount> iterator()

It would be inefficient but at least it is fool-proof. The operation is 
unlikely to be used very often.
