makePolygon

private java.awt.Shape makePolygon(java.util.Collection corners)

Constructs a polygon from a collection of Point2D objects.

Parameters:

corners - the corners of the polygon

Returns:

the polygon as a shape

sortPolyCorners

private java.util.Collection sortPolyCorners(java.util.Collection edges)

Sorts the endpoints of a collection of Line2D-objects, so that these points describe the contiuous, closed path defined by the lines. The collection of lines will be destroyed!

Parameters:

edges - a collection of Line2D-objects

Returns:

a collection of Point2D-objects, describing the polygon defined by the edges
