<div class="textblock"><p><code><a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a></code> classes support the concept of applying a <code><a class="el" href="classgeos_1_1geom_1_1GeometryComponentFilter.html">GeometryComponentFilter</a></code> filter to the <code><a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a></code>. The filter is applied to every component of the <code><a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a></code> which is itself a <code><a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a></code>. A <code><a class="el" href="classgeos_1_1geom_1_1GeometryComponentFilter.html">GeometryComponentFilter</a></code> filter can either record information about the <code><a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a></code> or change the <code><a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory. ">Geometry</a></code> in some way. <code><a class="el" href="classgeos_1_1geom_1_1GeometryComponentFilter.html">GeometryComponentFilter</a></code> is an example of the Gang-of-Four Visitor pattern. </p>
