Paths are decomposed during * construction into separate component non-overlapping parts, * empty pieces of the path are discarded, and then these * non-empty and non-overlapping properties are maintained * through all subsequent CAG operations. Outlines of different * component sub-paths may touch each other, as long as they * do not cross so that their enclosed areas overlap. * <li>The geometry of the path describing the outline of the * {@code Area} resembles the path from which it was * constructed only in that it describes the same enclosed * 2-dimensional area, but may use entirely different types * and ordering of the path segments to do so. * </ul> * Interesting issues which are not always obvious when using * the {@code Area} include: * <ul> * <li>Creating an {@code Area} from an unclosed (open) * {@code Shape} results in a closed outline in the * {@code Area} object. * <li>Creating an {@code Area} from a {@code Shape} * which encloses no area (even when "closed") produces an * empty {@code Area}. A common example of this issue * is that producing an {@code Area} from a line will * be empty since the line encloses no area. An empty * {@code Area} will iterate no geometry in its * {@code PathIterator} objects. * <li>A self-intersecting {@code Shape} may be split into * two (or more) sub-paths each enclosing one of the * non-intersecting portions of the original path. * <li>An {@code Area} may take more path segments to * describe the same geometry even when the original * outline is simple and obvious.
