3.2 The class hierarchy for DUIM-Extended-Geometry

3.2.2 Subclass of <path>

Three subclasses of <path> are exposed in the DUIM-Extended-Geometry library, each of which provides the ability to create instances of particular types of line. Their usage is relatively obvious.

<line>

This class is used to create straight lines between two points on a drawable object.

<elliptical-arc>

This class is used to create elliptical arcs (portions of an ellipse) on a drawable object.
<polyline>

This class is used to create lines that pass through an arbitrary set of coordinates. It produces a jagged line with vertices at each coordinate.
