A pure python bloomfilter implementation with JSON (de)serialisation and (zlib) compression
You can find a compatible JAVA implementation here: https://github.com/dirkmoors/java-bloomfilter
Example:
bf1 = BloomFilter(ideal_num_elements_n=1000000, error_rate_p=0.001)
bf1.add("Alabama")
bf1.add("Illinois")
bf1.add("Nevada")
bf1.add("RhodeIsland")
serialized_bloomfilter = bf1.toJSON()
#You can transmit the serialized_bloomfilter easily accross the network
bf2 = BloomFilter.fromJSON(serialized_bloomfilter)
for state in ("Alabama", "Illinois", "Nevada", "RhodeIsland"):
#Verify that the state MIGHT be in the bloomfilter
assert state in bf2
for state in ("Vermont", "Louisiana", "Mississippi", "Texas"):
#Verify that the state is DEFINITLY NOT in the bloomfilter
assert state not in bf2
