public class FnvHash {

private static final int kFNVOffset = (int) 2166136261l;
private static final int kFNVPrime = 16777619;

public static long fnvHashCode(final String str) {
int hash = kFNVOffset;

for (int i = 0; i < str.length(); i++) {
hash ^= (0x0000ffff & (int)str.charAt(i));
hash *= kFNVPrime;
}

return 0x00000000ffffffffl & (long) hash;
}

}
