Public Functions
-
NURBSSurfaceAttributeControl(NURBSSurfaceAttributeControl &&in_that)
The move constructor creates a NURBSSurfaceAttributeControl by transferring the underlying impl of the rvalue reference to this NURBSSurfaceAttributeControl thereby avoiding a copy and allocation.
- Parameters
in_that – An rvalue reference to a NURBSSurfaceAttributeControl to take the impl from.
-
NURBSSurfaceAttributeControl(NURBSSurfaceAttributeControl const &in_that)
Initializes a control tied to the same object as in_that.
-
explicit NURBSSurfaceAttributeControl(SegmentKey &in_seg)
Initializes a control tied to the segment in_seg.
-
inline virtual HPS::Type ObjectType() const
This function returns the type the object, as declared (if the object is derived, this does not give the true type of the derived object).
- Returns
The declared type of the object in question, which may differ from the true, underlying type.
-
NURBSSurfaceAttributeControl &operator=(NURBSSurfaceAttributeControl &&in_that)
The move assignment operator transfers the underlying impl of the rvalue reference to this NURBSSurfaceAttributeControl thereby avoiding a copy.
- Parameters
in_that – An rvalue reference to a NURBSSurfaceAttributeControl to take the impl from.
- Returns
A reference to this NURBSSurfaceAttributeControl.
-
NURBSSurfaceAttributeControl &operator=(NURBSSurfaceAttributeControl const &in_that)
Share the underlying smart-pointer of the NURBSSurfaceAttributeControl source.

in_that – The NURBSSurfaceAttributeControl source of the assignment.
- Returns
A reference to this NURBSSurfaceAttributeControl.
-
NURBSSurfaceAttributeControl &SetBudget(size_t in_budget)
