public class StrictAttitudeLegsSequence<L extends AttitudeLeg>
extends StrictLegsSequence<L>
implements AttitudeProvider

A “base” implementation of an attitude legs sequence. This implementation has strict legs which means legs cannot be simultaneous or overlap and are strictly ordered by starting date.

Since:

4.7

Returns the spin derivatives computation flag.

Returns:

the spin derivatives computation flag

sub
