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.

Detailed Description

The abstract class Geometry for 3D space is the root class of all geometric objects from the Geom package. It describes the common behavior of these objects when:

applying geometric transformations to objects, and
constructing objects by geometric transformation (including copying). Warning Only transformations which do not modify the nature of the geometry can be applied to Geom objects: this is the case with translations, rotations, symmetries and scales; this is also the case with gp_Trsf composite transformations which are used to define the geometric transformations applied using the Transform or Transformed functions. Note: Geometry defines the "prototype" of the abstract method Transform which is defined for each concrete type of derived object. All other transformations are implemented using the Transform method.
