Overview</h2>
<p>Main class is <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory.">geos::geom::Geometry</a>, from which all geometry types derive.</p>
<p>Construction and destruction of Geometries is done using <a class="el" href="classgeos_1_1geom_1_1GeometryFactory.html" title="Supplies a set of utility methods for building Geometry objects from CoordinateSequence or other Geom...">geos::geom::GeometryFactory</a>.</p>
<p>You'll feed it <a class="el" href="classgeos_1_1geom_1_1CoordinateSequence.html" title="The internal representation of a list of coordinates inside a Geometry.">geos::geom::CoordinateSequence</a> for base geometries or vectors of geometries for collections.</p>
<p>If you need to construct geometric shaped geometries, you can use geos::geom::GeometricShapeFactory.</p>
<p>GEOS version info (as a string) can be obtained using <a class="el" href="namespacegeos_1_1geom.html#acdb90e29e8ba4eeeb5860f2bb0bb9b0f" title="Return current GEOS version.">geos::geom::geosversion()</a>. The JTS version this release has been ported from is available throu <a class="el" href="namespacegeos_1_1geom.html#ac0f658bdb01fb543cd247febca7ab10c" title="Return the version of JTS this GEOS release has been ported from.">geos::geom::jtsport()</a>.</p>
<h2><a class="anchor" id="io_sect"></a>
Input / Output</h2>
<p>For WKT input/output you can use <a class="el" href="classgeos_1_1io_1_1WKTReader.html" title="WKT parser class; see also WKTWriter.">geos::io::WKTReader</a> and <a class="el" href="classgeos_1_1io_1_1WKTWriter.html" title="Outputs the textual representation of a Geometry. See also WKTReader.">geos::io::WKTWriter</a></p>
<p>For WKB input/output you can use <a class="el" href="classgeos_1_1io_1_1WKBReader.html" title="Reads a Geometry from Well-Known Binary format.">geos::io::WKBReader</a> and <a class="el" href="classgeos_1_1io_1_1WKBWriter.html" title="Writes a Geometry into Well-Known Binary format.">geos::io::WKBWriter</a></p>
<h2><a class="anchor" id="exc_sect"></a>
Exceptions</h2>
<p>Internal exceptions are thrown as instances <a class="el" href="classgeos_1_1util_1_1GEOSException.html" title="Base class for all GEOS exceptions.">geos::util::GEOSException</a> or derived classes. GEOSException derives from std::exception.</p>
<p>Note that prior to version 3.0.0, GEOSException were thrown by pointer, and did not derive from std::exception. </p>
