<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>Represents a list of contiguous line segments, and supports noding the segments. The line segments are represented by an array of <a class="el" href="">Coordinate</a>s. Intended to optimize the noding of contiguous segments by reducing the number of allocated objects. SegmentStrings can carry a context object, which is useful for preserving topological or parentage information. All noded substrings are initialized with the same context object. </p>
