Examples of java.awt.geom.GeneralPath

java.awt.geom.GeneralPath
The {@code GeneralPath} class represents a geometric path constructed from straight lines, and quadratic and cubic (Bézier) curves. It can contain multiple subpaths.
{@code GeneralPath} is a legacy final class which exactlyimplements the behavior of its superclass {@link Path2D.Float}. Together with {@link Path2D.Double}, the {@link Path2D} classesprovide full implementations of a general geometric path that support all of the functionality of the {@link Shape} and{@link PathIterator} interfaces with the ability to explicitlyselect different levels of internal coordinate precision.
Use {@code Path2D.Float} (or this legacy {@code GeneralPath}subclass) when dealing with data that can be represented and used with floating point precision. Use {@code Path2D.Double}for data that requires the accuracy or range of double precision. @version 1.64, 03/13/06 @author Jim Graham @since 1.2
