All Implemented Interfaces:
Shape, Serializable, Cloneable, org.gvsig.fmap.geom.primitive.IGeneralPathX
public class DefaultGeneralPathX extends org.gvsig.fmap.geom.primitive.GeneralPathX implements Shape, Cloneable, Serializable
The GeneralPathX class represents a geometric path constructed from straight lines, and quadratic and cubic (Bézier) curves. It can contain multiple subpaths.

The winding rule specifies how the interior of a path is determined. There are two types of winding rules: EVEN_ODD and NON_ZERO.

An EVEN_ODD winding rule means that enclosed regions of the path alternate between interior and exterior areas as traversed from the outside of the path towards a point inside the region.

A NON_ZERO winding rule means that if a ray is drawn in any direction from a given point to infinity and the places where the path intersects the ray are examined, the point is inside of the path if and only if the number of times that the path crosses the ray from left to right does not equal the number of times that the path crosses the ray from right to left.
