	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.

virtual void	Delete () const
	Memory deallocator for transient classes.

Detailed Description

An adaptor for curves with an applied transformation.

This class wraps a GeomAdaptor_Curve (or an Adaptor3d_CurveOnSurface) and applies a gp_Trsf transformation to all point and derivative evaluations. It serves as a base class for BRepAdaptor_Curve and allows batch evaluation with transformations in GeomGridEval_Curve.

The evaluation methods (Value, D0, D1, D2, D3, DN) are marked final to enable optimizations in grid evaluation.
