eas.math.geometry.Polygon2D
Implementierung eines Polygons. +++++++++++++++++++++++++++++++++++++ ++ TODO: KLASSENVERERBUNG ändern: ++ ++ "implements Iterable" statt "extends ArrayList". ++ ++ Dafür muss die ganz unten auskommentierte Methode implementiert werden. ++ Alle super(...) - Aufrufe müssen dann entfernt werden. ++ ++ Alle mit TODO kommentierten Methoden müssen überarbeitet werden, sodass ++ sie auf dem Path2D "polygonPath" arbeiten. Die Klasse Polygon2D soll in ++ diesem Sinn nur eine Hülle um Path2D sein, die einige Methoden anders ++ und einige zusätzlich zur Verfügung stellt. ++ ++ Neue Kommentare sollten auf englisch geschrieben werden. +++++++++++++++++++++++++++++++++++++ @author Lukas König
