      • nextDoc

        public int nextDoc()
        Description copied from class: DocIdSetIterator
        Advances to the next document in the set and returns the doc it is currently on, or DocIdSetIterator.NO_MORE_DOCS if there are no more docs in the set.
        NOTE: after the iterator has exhausted you should not call this method, as it may result in unpredicted behavior.
        Specified by:
        nextDoc in class DocIdSetIterator
      • advance

        public int advance​(int target)
                    throws java.io.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.

      • reset

        public void reset​(int[] positions,
                          int[] startOffsets,
                          int[] endOffsets,
                          BytesRef[] payloads)
      • getPayload

        public BytesRef getPayload()
        Description copied from class: PostingsEnum
        Returns the payload at this position, or null if no payload was indexed. You should not modify anything (neither members of the returned BytesRef nor bytes in the byte[]).

      • startOffset

        public int startOffset()
        Description copied from class: PostingsEnum
        Returns start offset for the current position, or -1 if offsets were not indexed.
        Specified by:
        startOffset in class PostingsEnum
      • endOffset

        public int endOffset()
        Description copied from class: PostingsEnum
        Returns end offset for the current position, or -1 if offsets were not indexed.

        endOffset in class PostingsEnum
      • cost

        public long cost()
        Description copied from class: DocIdSetIterator
        Returns the estimated cost of this DocIdSetIterator.

        This is generally an upper bound of the number of documents this iterator might match, but may be a rough heuristic, hardcoded value, or otherwise completely inaccurate.
