    • Method Detail

      • docID

        public int docID()
        Description copied from class: Scorable
        Returns the doc ID that is currently being scored.
        Specified by:
        docID in class Scorable
      • score

        private float score​(double distance)
      • computeMaxDistance

        private double computeMaxDistance​(float minScore,
                                          double previousMaxDistance)
        Inverting the score computation is very hard due to all potential rounding errors, so we binary search the maximum distance. The limit is set to 1 meter.
      • score

        public float score()
                    throws java.io.IOException
        Description copied from class: Scorable
        Returns the score of the current document matching the query.
        Specified by:
        score in class Scorable
        Throws:
        java.io.IOException
      • iterator

        public DocIdSetIterator iterator()
        Description copied from class: Scorer
        Return a DocIdSetIterator over matching documents.

        The returned iterator will either be positioned on -1 if no documents have been scored yet, DocIdSetIterator.NO_MORE_DOCS if all documents have been scored already, or the last document id that has been scored otherwise.

        The returned iterator is a view: calling this method several times will return iterators that have the same state.

        Specified by:
        iterator in class Scorer
      • getMaxScore

        public float getMaxScore​(int upTo)
        Description copied from class: Scorer
        Return the maximum score that documents between the last target that this iterator was shallow-advanced to included and upTo included.
        Specified by:
        getMaxScore in class Scorer
      • setMinCompetitiveScore

        public void setMinCompetitiveScore​(float minScore)
                                    throws java.io.IOException
        Description copied from class: Scorable
        Optional method: Tell the scorer that its iterator may safely ignore all documents whose score is less than the given minScore. This is a no-op by default.

        This method may only be called from collectors that use ScoreMode.TOP_SCORES, and successive calls may only set increasing values of minScore.

        Overrides:
        setMinCompetitiveScore in class Scorable
        Throws:
        java.io.IOException
