static RandomSample.Algorithm |
RandomSample.Algorithm.HASHING
Specifies a Fibonacci-style hash algorithm (see Knuth, S&S), which generates a less systematically distributed subset of the sampled collection than the traversal method, but requires a bounded priority queue the size of the sample, and creates an object containing a sampled value and its hash, for every element in the full set. |
static RandomSample.Algorithm |
RandomSample.Algorithm.TRAVERSAL
Specifies a methodical traversal algorithm, which is guaranteed to span the collection at least once, and never to return duplicates. |
