<p>If the parent component is an area edge, each side and the edge itself have a topological location. These locations are named</p>
<ul>
<li>ON: on the edge</li>
<li>LEFT: left-hand side of the edge</li>
<li>RIGHT: right-hand side</li>
</ul>
<p>If the parent component is a line edge or node, there is a single topological relationship attribute, ON.</p>
<p>The possible values of a topological location are {Location::UNDEF, Location::EXTERIOR, Location::BOUNDARY, Location::INTERIOR}</p>
<p>The labelling is stored in an array location[j] where where j has the values ON, LEFT, RIGHT </p>
