Public Functions

virtual bool Empty() const

Indicates whether this object has any values set on it.

true if no values are set on this object, false otherwise.

bool Equals(NURBSSurfaceAttributeKit const &in_kit) const

Check if the source NURBSSurfaceAttributeKit is equivalent to this object.

Parameters

in_kit – The source NURBSSurfaceAttributeKit to compare to this object.

Returns

true if the objects are equivalent, false otherwise.

NURBSSurfaceAttributeKit()

Initializes an empty kit.

NURBSSurfaceAttributeKit(NURBSSurfaceAttributeKit &&in_that)

The move constructor creates a NURBSSurfaceAttributeKit by transferring the underlying impl of the rvalue reference to this NURBSSurfaceAttributeKit thereby avoiding a copy and allocation.

Parameters

in_that – An rvalue reference to a NURBSSurfaceAttributeKit to take the impl from.

NURBSSurfaceAttributeKit(NURBSSurfaceAttributeKit const &in_kit)

The copy constructor creates a new NURBSSurfaceAttributeKit object that contains the same settings as the source object.

Parameters

in_kit – The source object to copy.

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.

bool operator!=(NURBSSurfaceAttributeKit const &in_kit) const

Check if the source NURBSSurfaceAttributeKit is not equivalent to this object.

Parameters

in_kit – The source NURBSSurfaceAttributeKit to compare to this object.

Returns

true if the objects are not equivalent, false otherwise.

NURBSSurfaceAttributeKit &operator=(NURBSSurfaceAttributeKit &&in_that)

The move assignment operator transfers the underlying impl of the rvalue reference to this NURBSSurfaceAttributeKit thereby avoiding a copy.

Parameters

in_that – An rvalue reference to a NURBSSurfaceAttributeKit to take the impl from.

Returns

A reference to this NURBSSurfaceAttributeKit.

Public Static Functions

static NURBSSurfaceAttributeKit GetDefault()
