Constructor. Creates a new object based on the specified shape type.
| in_type | Type of particle shape to create |
| ~CShape | ( | ) | [inline] |
Destructor.
Assignment operator.
| in_shape | Shape to copy |
| XSI::siICEShapeType GetType | ( | ) | [inline] |
Returns the shape type.
| ULONG GetReferenceID | ( | ) | [inline] |

| bool IsBranchSelected | ( | ) | [inline] |
Returns true if the referenced object is set as branch-selected. Applies to siICEShapeReference shape types only.
| bool operator== | ( | const CShape & | in_shape | ) | const [inline] |
Equality operator tests the strict equality of this shape with the specified shape.
| in_shape | Operand CShape. |
