deriveControlPoint()

static std::shared_ptr< Observable< std::shared_ptr< Point > > > luciad::ObservableBezierCurveUtil::deriveControlPoint ( const std::shared_ptr< Observable< std::shared_ptr< BezierCurve > > > &  observableBezierCurve )

static

Derives an Observable Point from the given observable bezier curve that represents the control point.

This observable point will be updated when the given observable bezier curve changes.

Notes:

• When the observable bezier curve contains a nullptr value, the observable point instance will contain a nullptr value too.
• Observable::setValue will throw an exception for derived instances.

Parameters

observableBezierCurve

an observable bezier curve from which to derive the point

Returns

a derived Observable

deriveEndPoint()

static std::shared_ptr< Observable< std::shared_ptr< Point > > > luciad::ObservableBezierCurveUtil::deriveEndPoint ( const std::shared_ptr< Observable< std::shared_ptr< BezierCurve > > > &  observableBezierCurve )

static

Derives an Observable Point from the given observable bezier curve that represents the end point.

This observable point will be updated when the given observable bezier curve changes.

Notes:

• When the observable bezier curve contains a nullptr value, the observable point instance will contain a nullptr value too.
• Observable::setValue will throw an exception for derived instances.

Parameters

observableBezierCurve

an observable bezier curve from which to derive the point

Returns

a derived Observable

deriveStartPoint()

static std::shared_ptr< Observable< std::shared_ptr< Point > > > luciad::ObservableBezierCurveUtil::deriveStartPoint ( const std::shared_ptr< Observable< std::shared_ptr< BezierCurve > > > &  observableBezierCurve )

static

Derives an Observable Point from the given observable bezier curve that represents the start point.

This observable point will be updated when the given observable bezier curve changes.

Notes:

• When the observable bezier curve contains a nullptr value, the observable point instance will contain a nullptr value too.
• Observable::setValue will throw an exception for derived instances.

Parameters

observableBezierCurve

an observable bezier curve from which to derive the point

Returns

a derived Observable
