The arcs form a contiguous line. The points on the path are referenced sequentially.
The general notion of a path is a sequence of contiguous arcs such that adjacent arcs are joined at start points or end points only. Furthermore, the points composing all of the arcs together must be able to be referenced (or accessed) in a one-directional, sequential order; this is accomplished by the appropriate choice for referencing for each of the individual orientedArcs composing the path.
If adjacent arcs which compose the path are defined as uniformBspline or piecewiseBezier, the duplicated points at the start and/or end points of the arcs are treated as single points and the curve is fit smoothly through the point from arc to arc.
