Simple constructor.

Method Detail

validate

public void validate(double version)

Check is all mandatory entries have been initialized.

This method should throw an exception if some mandatory entries are missing or not compatible with version number.

Specified by:

validate in interface Section

Overrides:

validate in class CommentsContainer

Parameters:

version - format version

getEndpoints

public AttitudeEndpoints getEndpoints()

Get the endpoints (i.e. frames A, B and their relationship).

Returns:

endpoints

getQuaternion

public Quaternion getQuaternion()

Get the quaternion.

Returns:

quaternion

setQ

public void setQ(int index,
                 double value)

Set quaternion component.

Parameters:

index - component index (0 is scalar part)

value - quaternion component

getQuaternionDot

public Quaternion getQuaternionDot()

Get the quaternion derivative.

Returns:

quaternion derivative

setQDot

public void setQDot(int index,
                    double derivative)

Set quaternion derivative component.

Parameters:

index - component index (0 is scalar part)

derivative - quaternion derivative component

hasRates

public boolean hasRates()

Check if the logical block includes rates.

Returns:

true if logical block includes rates
