### Constructor Detail

#### EuclideanDoublePoint

    public EuclideanDoublePoint(double[] point)

Build an instance wrapping an integer array.

The wrapped array is referenced, it is not copied.

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

### Method Detail

#### centroidOf

    public EuclideanDoublePoint centroidOf(Collection<EuclideanDoublePoint> points)

Returns the centroid of the given Collection of points.

Specified by:
  `centroidOf` in interface `Clusterable<EuclideanDoublePoint>`
Parameters:
  `points` - the Collection of points to compute the centroid of
Returns:
  the centroid of the given Collection of Points

#### distanceFrom

    public double distanceFrom(EuclideanDoublePoint p)

Returns the distance from the given point.

Specified by:
  `distanceFrom` in interface `Clusterable<EuclideanDoublePoint>`
Parameters:
  `p` - the point to compute the distance from
Returns:
  the distance from the given point

#### equals

    public boolean equals(Object other)

Overrides:
  `equals` in class `Object`

#### getPoint

    public double[] getPoint()

Get the n-dimensional point in integer space.

Returns:
  a reference (not a copy!) to the wrapped array

#### hashCode

    public int hashCode()

Overrides:
  `hashCode` in class `Object`

#### toString

    public String toString()

Overrides:
  `toString` in class `Object`
