        Throws:

      • refillPositions

        private void refillPositions()
                              throws java.io.IOException

      • getImpacts

        public Impacts getImpacts()
                           throws java.io.IOException
        Description copied from interface: ImpactsSource
        Get information about upcoming impacts for doc ids that are greater than or equal to the maximum of DocIdSetIterator.docID() and the last target that was passed to ImpactsSource.advanceShallow(int). This method may not be called on an unpositioned iterator on which ImpactsSource.advanceShallow(int) has never been called. NOTE: advancing this iterator may invalidate the returned impacts, so they should not be used after the iterator has been advanced.
        Throws:
        java.io.IOException
      • nextDoc

        public int nextDoc()
                    throws java.io.IOException
        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
        Throws:
        java.io.IOException
      • 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.

      • skipPositions

        private void skipPositions()

        Throws:

      • nextPosition

        public int nextPosition()
                         throws java.io.IOException
        Description copied from class: PostingsEnum
        Returns the next position, or -1 if positions were not indexed. Calling this more than PostingsEnum.freq() times is undefined.
        Specified by:
        nextPosition in class PostingsEnum
        Throws:
        java.io.IOException
      • 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.
        Specified by:
        endOffset in class PostingsEnum
      • 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[]).
        Specified by:
        getPayload 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.

        Specified by:
