      public DistinctVectorValues(FloatBuffer buffer, int startPosition, int endPosition)
      Analyze the specified FloatBuffer range using exact vector comparisons (without distinguishing 0 from -0) and instantiate the results.
      Parameters:
      buffer - the buffer to analyze (not null, unaffected)
      startPosition - the buffer position at which the vectors start (≥0, ≤endPosition, typically 0)
      endPosition - the buffer position at which the vectors end (≥startPosition, ≤capacity)

  • Method Details

    • countDistinct

      public int countDistinct()
      Count the number of distinct vectors in the original buffer range.
      Returns:
      the count (≥0)

    • findVvid

      public int findVvid(int vectorIndex)
      Find the ID of the indexed vector in the original buffer range.
      Parameters:
      vectorIndex - the index of the vector in the original buffer (≥0) which is typically a vertex ID
      Returns:
      an ID (≥0) or -1 if not found
