title: Are there any good Counting Bloom Filter implementations in Java?
body: <p>I'm looking for Counting Bloom Filter implementations in Java. I found the <a href="http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/util/bloom/CountingBloomFilter.html" rel="nofollow">Hadoop implementation</a> but as far as I can tell it lacks functionality to increase and decrease the count of a member. If it implements the Java Set interface as well this would be a nice feauture but not a must have.</p>
