  • Method Details

    • valuesEqual

      boolean valuesEqual(V vector1, int index1, V vector2, int index2)
      Checks if the vectors are equal at the given positions, given that the values at both positions are non-null.
      Parameters:
      vector1 - the first vector.
      index1 - index in the first vector.
      vector2 - the second vector.
      index2 - index in the second vector.
      Returns:
      true if the two values are considered to be equal, and false otherwise.

    • clone

      VectorValueEqualizer<V> clone()
      Creates a equalizer of the same type.
      Returns:
      the newly created equalizer.
