Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
int	GetRefCount () const noexcept
	Get the reference counter of this object.
void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
int	DecrementRefCounter () noexcept
	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.

bool & BRepTools_TrsfModification::IsCopyMesh ( )

Sets a flag to indicate the need to copy mesh.

overridevirtual

Returns true if the edge E has a new curve on surface on the face F. If a new curve exists:

C is the new geometric support of the edge,
L is the new location, and
Tol the new tolerance. If no new curve exists, this function returns false, and the values of C, L and Tol are not significant.

bool BRepTools_TrsfModification::NewParameter	(	const TopoDS_Vertex &	V,
		const TopoDS_Edge &	E,
		double &	P,
		double &	Tol )

overridevirtual

Returns true if the Vertex V has a new parameter on the edge E. If a new parameter exists:

P is the parameter, and
Tol is the new tolerance. If no new parameter exists, this function returns false, and the values of P and Tol are not significant.

◆ NewPoint()

bool BRepTools_TrsfModification::NewPoint	(	const TopoDS_Vertex &	V,
		gp_Pnt &	P,
		double &	Tol )

overridevirtual

Returns true if the vertex V has been modified. If the vertex has been modified:

P is the new geometry of the vertex, and
Tol is the new tolerance. If the vertex has not been modified this function returns false, and the values of P and Tol are not significant.

		bool &	RevFace )

overridevirtual

Returns true if the face F has been modified. If the face has been modified:

S is the new geometry of the face,
L is its new location, and
Tol is the new tolerance. RevWires is set to true when the modification reverses the normal of the surface (the wires have to be reversed). RevFace is set to true if the orientation of the modified face changes in the shells which contain it. For this class, RevFace returns true if the gp_Trsf associated with this modification is negative.
