Re: [BloomFilters] changes to BloomFilter

bf.getBits() * Long.BYTES may be as long as Math.Ceil( Shape.getNumberOfBits() / 8.0 ) or it may be shorter. I am building byte buffers of fixed length that is the maximum size that any valid bf.getBits() * Long.BYTES I need to know Shape.getNumberOfBytes(). The conversion is required for some B

Re: [BloomFilters] changes to BloomFilter

We are getting to the point where there are a lot of options that determine which implementation is "best". We could take a stab at creating a BloomFIlterFactory that takes a Shape as an argument and does a "finger in the air" guestimate of which implementation best fits. Store values in long blo

Re: [BloomFilters] changes to BloomFilter

You don't need Iterator iterator() as we have forEachCount( BitCountConsumer ) I guess we need something like add( Iterator) or add( Collection ) or add( Stream ) It would be nice if we could have a BitCountProducer class that we could just pass to an add() method. On Wed, Mar 18, 2020 at 11:

Re: [BloomFilters] changes to BloomFilter

On a slightly different note. CountingBloomFilters have no way to perform a reload. All other bloom filters you can dump the bits and reload (trivial) but if you preserve the counts from a bloom filter and want to reload them you can't. We need a constructor that takes the index,count pairs some
