Its interval of validity has closed endpoints except for AbsoluteDate.PAST_INFINITY and AbsoluteDate.FUTURE_INFINITY.

Parameters:

attitudeLaw - : provider of the attitude law

initialDate - : start date of the interval of validity

finalDate - : end date of the interval of validity

natureIn - leg nature

Method Detail

getTimeInterval

public AbsoluteDateInterval getTimeInterval()

Return the time interval of validity of the leg

Specified by:

getTimeInterval in interface Leg

Returns:

time interval of validity of the leg

getAttitudeLaw

public AttitudeLaw getAttitudeLaw()

Gets the attitude law provider associated to the current attitude leg.

Returns:

the AttitudeLaw of the current leg

getAttitude

public Attitude getAttitude(PVCoordinatesProvider pvProv,
                            AbsoluteDate date,
                            Frame frame)
                     throws PatriusException

Compute the attitude corresponding to an orbital state.

Specified by:

getAttitude in interface AttitudeProvider

Parameters:

pvProv - local position-velocity provider around current date

date - current date

frame - reference frame from which attitude is computed

Returns:

attitude attitude on the specified date and position-velocity state

Throws:

PatriusException - if attitude cannot be computed

truncate

public void truncate(AbsoluteDateInterval newIntervalOfValidity)
              throws PatriusException

Truncate the time interval of validity of the leg

Specified by:

truncate in interface Leg

Parameters:

newIntervalOfValidity - the new time interval

Throws:

PatriusException - if the new time interval is not included in the current time interval

getAttitude

                     throws PatriusException

Compute the attitude corresponding to an orbital state.

Specified by:

getAttitude in interface AttitudeProvider

Parameters:

orbit - current orbit

Returns:

attitude attitude on the current orbit

Throws:

PatriusException - if attitude cannot be computed

setSpinDerivativesComputation

public void setSpinDerivativesComputation(boolean computeSpinDerivatives)
