Method Detail

buildRotationDPFacade

public static RotationDPFacade buildRotationDPFacade(double[] data)

factory method.

Parameters:

data - describe the rotation. Can be either :

• three Cardan angles, in radians
• a vector and an angle, in radians
• an array of the matrix terms, line after line (R11, R12, R13, R21, R22, R23, R31, R32, R33)
• an angle. It will be a rotation of this angle around the z-axis, in radians

Returns:

a RotationDPFacade instance

Since:

1.0

computeDeviationTo

public final double computeDeviationTo(boolean absolute,
                                       DeviationProvider obj,
                                       boolean positive)

computes the deviation in angle between the stored rotation and the given one.

Specified by:

computeDeviationTo in interface DeviationProvider

Parameters:

absolute - absolute or relative deviation

obj - the DeviationProvider that should be a RotationDPFacade

positive - true if absolute value of deviations, false otherwise

Returns:

the deviation angle between the two values, in radians

Throws:

EphemerisComparatorRuntimeException - if the DeviationProvider is not of the correct type

DeviationProvider.computeDeviationTo(boolean, DeviationProvider, boolean)

getRotation

public final Rotation getRotation()

Returns:

the rotation
