<p>Base class for <a class="el" href="classgeos_1_1noding_1_1Noder.html">Noder</a>s which make a single pass to find intersections. This allows using a custom <a class="el" href="classgeos_1_1noding_1_1SegmentIntersector.html">SegmentIntersector</a> (which for instance may simply identify intersections, rather than insert them).</p>
<p>Last port: noding/SinglePassNoder.java rev. 1.3 (JTS-1.7)</p>
