public enum RotationOrder
extends Enum<RotationOrder>

This class is a utility representing a rotation order specification for Cardan or Euler angles specification. This class cannot be instanciated by the user. He can only use one of the twelve predefined supported orders as an argument to either the Rotation(RotationOrder, RotationConvention, double, double, double) constructor or the Rotation.getAngles(org.hipparchus.geometry.euclidean.threed.RotationOrder, org.hipparchus.geometry.euclidean.threed.RotationConvention) method. Since Hipparchus 1.7 this class is an enumerate class.

Method Detail

values

public static RotationOrder[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RotationOrder c : RotationOrder.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static RotationOrder valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

toString

public String toString()

Get a string representation of the instance.

Overrides:

toString in class Enum<RotationOrder>

Returns:

a string representation of the instance (in fact, its name)

getA1

public Vector3D getA1()

Get the axis of the first rotation.

Returns:

axis of the first rotation

getA2

public Vector3D getA2()

Get the axis of the second rotation.

Returns:

axis of the second rotation

getA3

public Vector3D getA3()

Get the axis of the second rotation.

Returns:

axis of the second rotation

getRotationOrder

public static RotationOrder getRotationOrder(String value)

Get the rotation order corresponding to a string representation.

Parameters:

value - name

Returns:

a rotation order object
