Note that this comparison does not attempt to restict its expressions to be meaningful. This means that it considers itself a valid filter as long as it contains two <b>geometry</b> sub-expressions. It is also slightly less restrictive than the OGC Filter specification because it does not require that one sub-expression be an geometry attribute and the other be a geometry literal. </p> <p> In other words, you may use this filter to compare two geometries in the same feature, such as: attributeA inside attributeB? You may also compare two literal geometries, although this is fairly meaningless, since it could be reduced (ie. it is always either true or false). This approach is very similar to that taken in the FilterCompare class. </p><P><P><DL><DT><B>Author:</B></DT> <DD>Rob Hranac, TOPP</DD><DT><B>Module:</B></DT><DD><CODE><B>module/main</B></CODE> (<A HREF="http://maven.geotools.fr/repository/org/geotools/gt2-main/"><CODE>gt2-main.jar</CODE></A>) (<A HREF="http://maven.geotools.fr/reports/main/index.html">Maven report</A>) (<A HREF="http://svn.geotools.org/geotools/tags/2.3.2/module/main/src/org/geotools/filter/GeometryFilterImpl.java">SVN head</A>)</DD><DT><B>'TODO:'</B></DT> <DD>REVISIT: make this class (and all filters) immutable, implement cloneable and return new filters when calling addLeftGeometry and addRightG Issues to think through: would be cleaner immutability to have constructor called with left and right Geometries, but this does not jive with SAX parsing, which is one of the biggest uses of filters. But the alternative is not incredibly efficient either, as there will be two filters that are just thrown away every time we make a full geometry filter. These issues extend to most filters, as just about all of them are mutable when creating them. Other issue is that lots of code will need to be changed for immutability. (comments by cholmes) - MUTABLE FACTORIES! Sax and immutability.</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%"
