<p>Processes possible intersections detected by a <a class="el" href="classgeos_1_1noding_1_1Noder.html" title="Computes all intersections between segments in a set of SegmentString.">Noder</a>. </p>
<p>The <a class="el" href="classgeos_1_1noding_1_1SegmentIntersector.html" title="Processes possible intersections detected by a Noder.">SegmentIntersector</a> is passed to a <a class="el" href="classgeos_1_1noding_1_1Noder.html" title="Computes all intersections between segments in a set of SegmentString.">Noder</a>. The addIntersections method is called whenever the <a class="el" href="classgeos_1_1noding_1_1Noder.html" title="Computes all intersections between segments in a set of SegmentString.">Noder</a> detects that two SegmentStrings <em>might</em> intersect. This class may be used either to find all intersections, or to detect the presence of an intersection. In the latter case, Noders may choose to short-circuit their computation by calling the isDone method. This class is an example of the <em>Strategy</em> pattern.</p>
