<p>Validates that a collection of <a class="el" href="classgeos_1_1noding_1_1SegmentString.html">SegmentString</a>s is correctly noded. </p>
<p>Uses indexes to improve performance. Does NOT check a-b-a collapse situations. Also does not check for endpt-interior vertex intersections. This should not be a problem, since the noders should be able to compute intersections between vertices correctly. User may either test the valid condition, or request that a <a class="el" href="">TopologyException</a> be thrown.</p>
