<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>Computes all intersections between segments in a set of <a class="el" href="classgeos_1_1noding_1_1SegmentString.html" title="An interface for classes which represent a sequence of contiguous line segments.">SegmentString</a>. </p>
<p>Intersections found are represented as <a class="el" href="classgeos_1_1noding_1_1SegmentNode.html">SegmentNode</a>s and added to the <a class="el" href="classgeos_1_1noding_1_1SegmentString.html">SegmentString</a>s in which they occur. As a final step in the noding a new set of segment strings split at the nodes may be returned.</p>
<p>Last port: noding/Noder.java rev. 1.8 (JTS-1.7)</p>
<p>TODO: this was really an interface, we should avoid making it a Base class </p>
