<div class="textblock"><p>Validates that a collection of <a class="el" href="classgeos_1_1noding_1_1SegmentString.html">SegmentString</a>s is correctly noded. </p>
<p>Indexing is used to improve performance. By default validation stops after a single non-noded intersection is detected. Alternatively, it can be requested to detect all intersections by using <code>setFindAllIntersections(boolean)</code>.</p>
<p>The validator does not check for topology collapse situations (e.g. where two segment strings are fully co-incident).</p>
<p>The validator checks for the following situations which indicated incorrect noding:</p>
<ul>
<li>Proper intersections between segments (i.e. the intersection is interior to both segments)</li>
<li>Intersections at an interior vertex (i.e. with an endpoint or another interior vertex)</li>
</ul>
<p>The client may either test the <a class="el" href="classgeos_1_1noding_1_1FastNodingValidator.html#aad541ae8ff8cf433d24e3ec4b22fa5cd">isValid()</a> condition, or request that a suitable <a class="el" href="classgeos_1_1util_1_1TopologyException.html">TopologyException</a> be thrown. </p>
