  `NURBSCurveKey`()

    The default constructor creates an uninitialized NURBSCurveKey object. The Type() function will return Type::None.

  explicit `NURBSCurveKey`(Key const &in_that)

    This constructor creates a NURBSCurveKey object that shares the underlying smart-pointer of the source Key. The copy will only be successful if the source key is really an upcast of a NURBSCurve key. Otherwise the copy will fail and the resulting NURBSCurveKey will be invalid.

    Parameters: | in_key – The source Key to copy.

  `NURBSCurveKey`(NURBSCurveKey &&in_that)

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

    Parameters: | in_that – An rvalue reference to a NURBSCurveKey to take the impl from.

  `NURBSCurveKey`(NURBSCurveKey const &in_that)

    The copy constructor creates a NURBSCurveKey object that shares the underlying smart-pointer of the source NURBSCurveKey.

    Parameters: | in_that – The source NURBSCurveKey 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.

  NURBSCurveKey &`operator=`(NURBSCurveKey &&in_that)

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

    Parameters: | in_that – An rvalue reference to a NURBSCurveKey to take the impl from.
    Returns: | A reference to this NURBSCurveKey.
