This is an implementation by Viliam Holub of the fast non-cryptographic murmurhash2 algorithm.

It is written in Java and is implemented in both 32 and 64-bit versions.

If you want the latest in the world of murmur, check out Guava's Hashing class, which has 32 and 128 bit implementations of murmur3.

building

Build a package with maven:

mvn package

Run the tests:

mvn test
