      • ZFastTrieDistributor

        public ZFastTrieDistributor​(java.lang.Iterable<? extends T> elements,
                            int log2BucketSize,
                            it.unimi.dsi.bits.TransformationStrategy<? super T> transformationStrategy,

                     throws java.io.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:
        java.io.IOException
