This needs to be done as an Integrity Test to account for both the LineString and Polygon FeatureTypes being changed in the same Transaction. Further more the test will need to be run if either (or both) FeatureTypes are changed: a new line may be created outside of a polygon, or a polygon may be deleted leaving a line uncovered. If we a bit smarter about these relationship we could run this Validation Test only on LineString insert/modify or Polygon modify/delete but life is too short, and there is always another release. </p> <p> To do this with any sense of efficiency we will need to take an initial run through the Polygon FeatureSource to build an Index of FeatureID by BoundingBox. We can use this to selectively query the Polygon FeatureSource as we work through the LineString content. </p> <p> TODO: David Zweirs Read This! Talk to Justin or any of the JUMP experts who have experence in implementing JTS indexes. You can use the "layers" Map to store the generated index, or make up an API to do so as part of the ValidationProcessor. At the very least your index will last for the current validation "run" - which is all that can be expected. What really needs to be done is punt the index generation off to the database/DataStore anything else won't scale (don't you love GIS problems). </p><P><P><DL><DT><B>Author:</B></DT> <DD>Jody Garnett, Refractions Research, Inc., $Author: dmzwiers $ (last modification)</DD><DT><B>Module:</B></DT><DD><CODE><B>ext/validation</B></CODE> (<A HREF="http://maven.geotools.fr/repository/org/geotools/gt2-validation/"><CODE>gt2-validation.jar</CODE></A>) (<A HREF="http://maven.geotools.fr/reports/validation/index.html">Maven report</A>) (<A HREF="http://svn.geotools.org/geotools/tags/2.3.2/ext/validation/src/org/geotools/validation/spatial/LineCoveredByPolygonValidation.java">SVN head</A>)</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR></TABLE> <A NAME="fields_inherited_from_class_Validation"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from interface <A HREF="../../../../org/geotools/validation/Validation.html" title="interface in org.geotools.validation">Validation</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../../org/geotools/validation/Validation.html#ALL">ALL</A>, <A HREF="../../../../org/geotools/validation/Validation.html#PRIORITY_COMPLEX">PRIORITY_COMPLEX</A>, <A HREF="../../../../org/geotools/validation/Validation.html#PRIORITY_INVOLVED">PRIORITY_INVOLVED</A>, <A HREF="../../../../org/geotools/validation/Validation.html#PRIORITY_SIMPLE">PRIORITY_SIMPLE</A>, <A HREF="../../../../org/geotools/validation/Validation.html#PRIORITY_TRIVIAL">PRIORITY_TRIVIAL</A></CODE></TD></TR></TABLE> <!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Constructor Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../../org/geotools/validation/spatial/LineCoveredByPolygonValidation.html#LineCoveredByPolygonValidation()">LineCoveredByPolygonValidation</A></B>()</CODE><BR> No argument constructor, required by the Java Bean Specification.</TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2">⌨️ 快捷键说明
