Class BloomFilter (3.17.0)

public final class BloomFilter extends GeneratedMessageV3 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.
