Standard_Transient *	This () const

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

Describes an axis in 2D space. An axis is defined by:

• its origin, also termed the "Location point" of the axis,
• its unit vector, termed the "Direction" of the axis. Note: Geom2d_AxisPlacement axes provide the same kind of "geometric" services as gp_Ax2d axes but have more complex data structures. The geometric objects provided by the Geom2d package use gp_Ax2d objects to include axes in their data structures, or to define an axis of symmetry or axis of rotation. Geom2d_AxisPlacement axes are used in a context where they can be shared by several objects contained inside a common data structure.
