This class is auxiliary class (data storage) used in ComposeShell. It is intended for representing segment of the wire (or whole wire). The segment itself is represented by ShapeExtend_WireData. In addition, some associated data necessary for computations are stored: More...

This class is auxiliary class (data storage) used in ComposeShell. It is intended for representing segment of the wire (or whole wire). The segment itself is represented by ShapeExtend_WireData. In addition, some associated data necessary for computations are stored:
TopAbs_FORWARD and TopAbs_REVERSED - says that segment was traversed once in the corresponding direction, and hence it should be traversed once more in opposite direction;
TopAbs_EXTERNAL - the segment was not yet traversed in any direction (i.e. not yet used as boundary)
TopAbs_INTERNAL - the segment was traversed in both directions and hence is out of further work.
Segments of initial bounding wires are created with orientation REVERSED (for outer wire) or FORWARD (for inner wires), and segments of splitting seams - with orientation EXTERNAL.
