public static final class BloomFilter.Builder extends GeneratedMessageV3.Builder<BloomFilter.Builder> implements BloomFilterOrBuilder
A bloom filter (https://en.wikipedia.org/wiki/Bloom_filter).
The bloom filter hashes the entries with MD5 and treats the resulting 128-bit hash as 2 distinct 64-bit hash values, interpreted as unsigned integers using 2's complement encoding.
These two hash values, named h1
and h2
, are then used to compute the
hash_count
hash values using the formula, starting at i=0
:
h(i) = h1 + (i * h2)
These resulting values are then taken modulo the number of bits in the bloom filter to get the bits of the bloom filter to test for the given entry.
