distance

public double distance(Point2D_I32 a)

distance2

public int distance2(Point2D_I32 a)

Returns the Euclidean distance squared from 'this' to 'a'. No floating point operations are used.

d² = (this.x-a.x)² + (this.y-a.y)²

Parameters:

a - Point that distance is computed from.

Returns:

Euclidean distance squared.

copy

public Point2D_I32 copy()

Description copied from class: GeoTuple

Generic copy routine. It is recommended that this be overridden with a faster implementation.

Specified by:

copy in class GeoTuple<Point2D_I32>

Returns:

An exact copy of this GeoTuple.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getDimension

public int getDimension()

Description copied from class: GeoTuple

The dimensionality of space the tuple is contained in and the number of values it has.

Specified by:

getDimension in class GeoTuple<Point2D_I32>

Returns:

Dimensionality of the object.

createNewInstance

public Point2D_I32 createNewInstance()

Description copied from class: GeoTuple

Creates a new tuple instance of the same type.

Specified by:

createNewInstance in class GeoTuple<Point2D_I32>

Returns:

new tuple instance.
