Public Member Functions
virtual void	TwistValue (Angle twist) noexcept=0
	Set twist value.
virtual Angle	TwistValue () const noexcept=0
	Get twist value.
virtual const Data &	GetData () const noexcept=0
virtual void	Create (const Data &data) noexcept=0
Public Member Functions inherited from trax::RoadwayTwist
virtual const char *	TypeName () const noexcept=0
	Name for the object type that implements this interface.
virtual TwistType	GetTwistType () const noexcept=0
virtual std::unique_ptr< RoadwayTwist >	Clone () const =0
	Make a clone from this object.
virtual bool	IsValid () const noexcept=0
virtual Angle	Twist (Length s) const =0
virtual AnglePerLength	D1 (Length s) const =0
virtual bool	ZeroFlip (bool bActive) noexcept=0
virtual void	Flip () noexcept=0
	Flips the effect of the twist along the track. After calling this function, the Twist() and D1() methods will give pi - Twist(Track::GetLength() - s) and -D1(Track::GetLength() - s). Calling Flip() a second time will nullify the effect.
virtual void	Mirror () noexcept=0
	Multiplies all twist angle by -1.
virtual bool	Offset (Angle offset) noexcept=0
	Adds a global offset angle to the Twist.
virtual bool	IsDynamic () const noexcept=0
	A twist is dynamic if it relates to geometry global to the track.
virtual bool	IsDirectionalConstant () const noexcept=0
	Find wether the twist is directional only offsetted by a constant.
virtual bool	IsConstant () const noexcept=0
virtual void	Freeze (bool bFreeze=true) noexcept=0
	Freezes the twist, so that dynamic twists like DirectionalTwist don't update anymore.
virtual bool	IsFrozen () const noexcept=0
virtual bool	IsNull () const noexcept=0
virtual bool	Equals (const RoadwayTwist &toTwist, Angle epsilon_angle=epsilon__angle) const noexcept=0
	Comparison.
virtual void	OnAttach (const TrackBuilder &track) noexcept=0
	Called on attachment to a track.
virtual void	OnDetach () noexcept=0
	Called on detachment from a track.
virtual Angle	DoTwist (Length) const =0
virtual AnglePerLength	DoD1 (Length) const =0
	RoadwayTwist (RoadwayTwist &&)=delete
RoadwayTwist &	operator= (const RoadwayTwist &)=delete
RoadwayTwist &	operator= (RoadwayTwist &&)=delete

Static Public Member Functions
static dclspc std::unique_ptr< ConstantTwist >	Make () noexcept
	Makes a ConstantTwist object.
static dclspc std::unique_ptr< ConstantTwist >	Make (const RoadwayTwist &fromTwist) noexcept
	Makes a ConstantTwist object from another twist.
Static Public Member Functions inherited from trax::RoadwayTwist
static dclspc std::unique_ptr< RoadwayTwist >	Make (TwistType type) noexcept
	Makes a RoadwayTwist object.
static dclspc std::unique_ptr< RoadwayTwist >	Make (TwistType type, const RoadwayTwist &fromTwist) noexcept
	Makes a RoadwayTwist object from another twist.
