    • ZFastTrieDistributor

      public ZFastTrieDistributor(Iterable<? extends T> elements, int log2BucketSize, it.unimi.dsi.bits.TransformationStrategy<? super T> transformationStrategy, BucketedHashStore<it.unimi.dsi.bits.BitVector> bucketedHashStore) throws IOException
      Creates a distributor based on a z-fast trie.
      Parameters:
      elements - the elements among which the trie must be able to rank.
      log2BucketSize - the logarithm of the size of a bucket.
      transformationStrategy - a transformation strategy that must turn the elements in elements into a list of distinct, lexicographically increasing (in iteration order) bit vectors.
      bucketedHashStore - a store containing the keys already transformed into bit vectors.
      Throws:
      IOException
