    - #### DoublePoint

          public DoublePoint(double[] point)

      Build an instance wrapping an double array.

      The wrapped array is referenced, it is not copied.

      Parameters:
        `point` - the n-dimensional point in double space

    - #### DoublePoint

          public DoublePoint(int[] point)

      Build an instance wrapping an integer array.

      The wrapped array is copied to an internal double array.

      Parameters:
        `point` - the n-dimensional point in integer space

  - ### Method Detail

    - #### getPoint

          public double[] getPoint()

      Gets the n-dimensional point.
      Specified by:
        `getPoint` in interface `Clusterable`
      Returns:
        the point array

    - #### equals

          public boolean equals(Object other)

      Overrides:
        `equals` in class `Object`

    - #### hashCode

          public int hashCode()

      Overrides:
        `hashCode` in class `Object`

    - #### toString

          public String toString()
