Class Sphere1D

java.lang.Object

org.apache.commons.math3.geometry.spherical.oned.Sphere1D

All Implemented Interfaces:

java.io.Serializable, Space

public class Sphere1D
extends java.lang.Object
implements java.io.Serializable, Space

This class implements a one-dimensional sphere (i.e. a circle).

We use here the topologists definition of the 1-sphere (see Sphere on MathWorld), i.e. the 1-sphere is the one-dimensional closed curve defined in 2D as x²+y²=1.

Since:

3.3

Method Detail

getInstance

public static Sphere1D getInstance()

Get the unique instance.

Returns:

the unique instance

getDimension

public int getDimension()

Get the dimension of the space.

Specified by:

getDimension in interface Space

Returns:

dimension of the space

getSubSpace

public Space getSubSpace()
                  throws Sphere1D.NoSubSpaceException

Get the n-1 dimension subspace of this space.

As the 1-dimension sphere does not have proper sub-spaces, this method always throws a Sphere1D.NoSubSpaceException

Specified by:

getSubSpace in interface Space

Returns:

nothing

Throws:

Sphere1D.NoSubSpaceException - in all cases
