Class CheckerPolygon

java.lang.Object

com.luchersol.core.specialized_checkers.math.CheckerPolygon

All Implemented Interfaces:

InterfaceChecker<AbstractChecker<Polygon,CheckerPolygon>,Polygon>

public class CheckerPolygon
extends AbstractChecker<Polygon,CheckerPolygon>

A specialized checker for Polygon instances, providing fluent API methods to assert properties of 2D polygonal shapes.

Typical usage:

 int[] xpoints = {0, 50, 100};
 int[] ypoints = {0, 100, 0};

 CheckerPolygon checker = CheckerPolygon.check(xpoints, ypoints, 3)
     // future validations can be chained here
     .self();
 

This class supports multiple factory methods to create a checker directly from a Polygon instance or from arrays of coordinates, making it flexible for geometric validations in a fluent and readable style.
