    • encode

      boolean encode(long[] current, long[] next)
      Encode one or more stereo elements based on the current invariants. If any stereo element are uncovered then the corresponding value in the next[] array is modified.
      Parameters:
      current - current invariants
      next - next invariants
      Returns:
      whether any stereo configurations were encoded

    • reset

      void reset()
      Reset the stereo-encoders, any currently perceived configurations will be re-activated.
