Method

inthash(int state1, int state2, int numStates1)
hash 
return state1 + numStates1 * state2;
inthash(int val)
hash 
return FNVhash32(val);
inthash(int value)
hash 
return (value * KnuthsAValue) >>> (INT_SIZE - K);
inthash(int x, int y)
hash 
int h = 31;
h = h * 97 + x;
h *= 17;
h = h * 97 + y;
h *= 17;
return h;
longhash(long key)
hash 
key ^= key >>> 33;
key *= 0xff51afd7ed558ccdL;
key ^= key >>> 33;
key *= 0xc4ceb9fe1a85ec53L;
key ^= key >>> 33;
return key;
longhash(long mover, long enemy)
Hash 2 longs into a single long, using a mixing function derived from Murmur. 
final long a = murmurMix(mover ^ murmurMix(enemy));
return a ^ (a >>> 47);
inthash(Object a, Object b)
hash 
return hashCombine(a.hashCode(), b.hashCode());
inthash(Object key, int limit)
hash 
if (limit == 1) {
    return 0;
int hashValue = hash(key.hashCode());
if (hashValue == Integer.MIN_VALUE) {
    hashValue -= 1;
hashValue = Math.abs(hashValue);
...
inthash(Object o)
hash 
return o == null ? 0 : o.hashCode();
inthash(Object obj)
hash 
final int prime = 31;
int result = 1;
result = prime * result + ((obj == null) ? 0 : obj.hashCode());
return result;
