Method Detail

getIntersection

public static Point getIntersection(Line2D line1,
                                    Line2D line2)
                             throws MultipleIntersectionException

Returns the intersection point of two lines.

Parameters:

line1 - First line

line2 - Second line

Returns:

The Point object where the two lines intersect. This method returns null if the two lines do not intersect.

Throws:

MultipleIntersectionException - when the two lines have more than one intersection point.

MultipleIntersectionException

getIntersection

public static Point getIntersection(Line2D line,
                                    GeneralPath path)

Returns the intersection point of a line and a GeneralPath. Given that a line can intersect more than one segment of a GeneralPath, this method will return the intersection point of the first segment, returned by a PathIterator, and the line. No consideration is taken if the line intersects more than one segment of the GeneralPath since this is internally used by salvo.jesus.graph.VisualEdge wherein the edge of a line will intersect only one segment of the VisualVertex's GeneralPath.

Parameters:

line1 - First line

path - GeneralPath representing line segments

Returns:

The Point object where the line and the GeneralPath object intersect. This method returns null if they do not intersect.
