<h1>PolyNode</h1>
<br>
<p class="Body"> <b>PolyNodes</b> are encapsulated within a <a href="../PolyTree/_Body.htm"><b>PolyTree</b></a> container, and together provide a data structure representing the parent-child relationships of polygon contours returned by Clipper's <a href="../Clipper/Methods/Execute.htm"><b>Execute</b></a> method.<br><br> A <b>PolyNode</b> object represents a single polygon. Its <a href="./Properties/IsHole.htm">IsHole</a> property indicates whether it's an <a href="../../../../Overview/_Body.htm#terminology">outer</a> or a <a href="../../../../Overview/_Body.htm#terminology">hole</a>. PolyNodes may own any number of PolyNode children (<a href="./Properties/Childs.htm"><b>Childs</b></a>), where children of outer polygons are holes, and children of holes are (nested) outer polygons.<br><br> </p>
