CControlPointRefArray Class Reference

Detailed Description

An array of ControlPoint object references representing the NurbsCurve or NurbsSurface control points.

This specialized array is returned by NurbsCurve::GetControlPoints and NurbsSurface::GetControlPoints, it is not meant to be created and modified in user-defined functions. If you want to add and remove arbitrary items to a collection, you must use a CRefArray instead.

Member Function Documentation

CRef GetItem ( LONG  in_index) const [virtual]

Returns the NurbsCurve object at a specified index in the array.

in_indexThe index of the NurbsCurve.
A reference to the NurbsCurve object.

Reimplemented from CPointRefArray.

CRef GetItem ( const CString in_name) const [virtual]

Returns the NurbsCurve object in the array matching the specified name.

in_nameThe name of the NurbsCurve.
A reference to the NurbsCurve object.

Reimplemented from CPointRefArray.

LONG GetCount ( ) const [virtual]

Returns the number of NurbsSurface objects in the array.

The number of NurbsSurface objects.

Reimplemented from CPointRefArray.

bool IsValid ( ) const [virtual]

Returns whether this array is a valid object.

true if valid, false otherwise.

Reimplemented from CPointRefArray.

CStatus GetArray ( MATH::CVector4Array out_vPositions) const

Returns an array of control points for this nurbs component.

Return values:
out_vPositionsAn array of positions for the control points.
CStatus::OK success.
CStatus::Fail other failure.
CStatus PutArray ( MATH::CVector4Array in_vPositions)

Sets an array of control points for this nurbs component. This function can only be used within a compiled operator or if no operators are attach to this geometry.

in_vPositionsThe new positions for the control points.
CStatus::OK success.
CStatus::CStatus::AccessDenied function used outside of a plug-in operator context.
CStatus Dimension ( siNurbsDirection  in_siDirection,
LONG &  out_lDimension 
) const

Returns the size of the ControlPoint reference array in a particular direction. For NurbsCurves use siUDirection.

in_siDirectionDirection of dimension required (one of the siNurbsDirection values).
Return values:
out_lDimensionThe actual dimension.
CStatus::OK success.
CStatus::InvalidArgument if the direction is invalid for this type of component (for example, siVDirection for a NurbsCurve).
