      • vectorValue

        public float[] vectorValue()
                            throws IOException
        Description copied from class: FloatVectorValues
        Return the vector value for the current document ID. It is illegal to call this method when the iterator is not positioned: before advancing, or after failing to advance. The returned array may be shared across calls, re-used, and modified as the iterator advances.

      • advance

        public int advance​(int target)
                    throws IOException
        Description copied from class: DocIdSetIterator
        Advances to the first beyond the current whose document number is greater than or equal to target, and returns the document number itself. Exhausts the iterator and returns DocIdSetIterator.NO_MORE_DOCS if target is greater than the highest document number in the set.

        The behavior of this method is undefined when called with target ≤ current , or after the iterator has exhausted. Both cases may result in unpredicted behavior.

        When target > current it behaves as if written:

         int advance(int target) {
           int doc;
           while ((doc = nextDoc()) < target) {
           return doc;
        Some implementations are considerably more efficient than that.

        NOTE: this method may be called with DocIdSetIterator.NO_MORE_DOCS for efficiency by some Scorers. If your implementation cannot efficiently determine that it should exhaust, it is recommended that you check for that value in each call to this method.

      • getAcceptOrds

        public Bits getAcceptOrds​(Bits acceptDocs)
        Description copied from interface: RandomAccessVectorValues
        Returns the Bits representing live documents. By default, this is an identity function.
        acceptDocs - the accept docs
