There is a code example here: <a href="http://docs.geotools.org/latest/userguide/library/main/collection.html#join" rel="nofollow">http://docs.geotools.org/latest/userguide/library/main/collection.html#join</a> It shows how to nest loops: <pre><code>void polygonInteraction() { SimpleFeatureCollection polygonCollection = null; SimpleFeatureCollection fcResult = null; final SimpleFeatureCollection found = FeatureCollections.newCollection(); FilterFactory2 ff = CommonFactoryFinder.getFilterFactory2(); SimpleFeature feature = null; Filter polyCheck = null; Filter andFil = null; Filter boundsCheck = null; String qryStr = null; SimpleFeatureIterator it = polygonCollection.features(); try { while (it.hasNext()) { feature = it.next(); BoundingBox bounds = feature.getBounds(); boundsCheck = ff.bbox(ff.property("the_geom"), bounds); Geometry geom = (Geometry) feature.getDefaultGeometry(); polyCheck = ff.intersects(ff.property("the_geom"), ff.literal(geom)); andFil = ff.and(boundsCheck, polyCheck); try { fcResult = featureSource.getFeatures(andFil); // go through results and copy out the found features fcResult.accepts(new FeatureVisitor() { public void visit(Feature feature) { found.add((SimpleFeature) feature); } }, null); } catch (IOException e1) { System.out.println("Unable to run filter for " + feature.getID() + ":" + e1); continue; } } } finally { it.close(); } } </code></pre> If you want to ignore some features you have already visited, and skip content:: <pre><code>HashSet<FeatureId> skip = new HashSet<FeatureId>(); ... if( skip.contains( feature.getId() ) ) continue; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
