| Add(HLLPolicy, Exp, Exp) | Create expression that adds list values to a HLL set and returns HLL set. The function assumes HLL bin already exists. |
| Add(HLLPolicy, Exp, Exp, Exp) | Create expression that adds values to a HLL set and returns HLL set. If HLL bin does not exist, use indexBitCount to create HLL bin. |
| Add(HLLPolicy, Exp, Exp, Exp, Exp) | Create expression that adds values to a HLL set and returns HLL set. If HLL bin does not exist, use indexBitCount and minHashBitCount to create HLL set. |
| Describe | Create expression that returns indexBitCount and minHashBitCount used to create HLL bin in a list of longs. list[0] is indexBitCount and list[1] is minHashBitCount. |
| GetCount | Create expression that returns estimated number of elements in the HLL bin. |
| GetIntersectCount | Create expression that returns estimated number of elements that would be contained by the intersection of these HLL objects. |
| GetSimilarity | Create expression that returns estimated similarity of these HLL objects as a 64 bit float. |
| GetUnion | Create expression that returns a HLL object that is the union of all specified HLL objects in the list with the HLL bin. |
| GetUnionCount | Create expression that returns estimated number of elements that would be contained by the union of these HLL objects. |
| Init(HLLPolicy, Exp, Exp) | Create expression that creates a new HLL or resets an existing HLL. |
| Init(HLLPolicy, Exp, Exp, Exp) | Create expression that creates a new HLL or resets an existing HLL with minhash bits. |
| MayContain | Create expression that returns one if HLL bin may contain all items in the list. |
