CKnotArray& operator= | ( | const CKnotArray & | in_obj | ) |
Creates an object from another object. The newly created object is set to empty if the input object is not compatible.
in_obj | constant class object. |
CKnotArray& operator= | ( | const CRef & | in_ref | ) |
Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.
in_ref | constant class object. |
Reimplemented from SIObject.
bool IsA | ( | siClassID | in_classID | ) | const [virtual] |
Returns true if a given class type is compatible with the underlying reference object.
in_classID | Class type. |
Reimplemented from SIObject.
siClassID GetClassID | ( | ) | const [virtual] |
Returns the class type of this array
Reimplemented from SIObject.
double GetItem | ( | LONG | in_index | ) | const |
Returns the value of a knot at a given index, if the index is invalid or the CKnotArray is invalid it will return DBL_MAX instead.
in_index | The index of the Knot. |

Returns an array object containing the knot values.
LONG GetCount | ( | ) | const |
Returns the number of Knot objects in the array.
CStatus GetClosed | ( | bool & | out_bClosed | ) | const |
Returns true if the parametric domain is closed.
out_bClosed | Return value. |

Returns the parameterization.
out_siParameterization | The parameterization. |
CStatus GetMultiplicity | ( | double | in_dKnotValue, |
LONG & | out_lMultiplicity | ||
) | const |
Returns the multiplicity at a certain knot value.
in_dKnotValue | The knot value for which we want to know the multiplicity. |
