<p><a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory.">Geometry</a> classes support the concept of applying a <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory.">Geometry</a> filter to the <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory.">Geometry</a>. </p>
<p>In the case of <a class="el" href="classgeos_1_1geom_1_1GeometryCollection.html" title="Represents a collection of heterogeneous Geometry objects.">GeometryCollection</a> subclasses, the filter is applied to every element <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory.">Geometry</a>. A <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory.">Geometry</a> filter can either record information about the <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory.">Geometry</a> or change the <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory.">Geometry</a> in some way. <a class="el" href="classgeos_1_1geom_1_1Geometry.html" title="Basic implementation of Geometry, constructed and destructed by GeometryFactory.">Geometry</a> filters implement the interface <a class="el" href="classgeos_1_1geom_1_1GeometryFilter.html" title="Geometry classes support the concept of applying a Geometry filter to the Geometry.">GeometryFilter</a>. (<a class="el" href="classgeos_1_1geom_1_1GeometryFilter.html" title="Geometry classes support the concept of applying a Geometry filter to the Geometry.">GeometryFilter</a> is an example of the Gang-of-Four Visitor pattern). </p>
