Body
<p>The code for the answer from the previous question was</p> <pre class="lang-java prettyprint-override"><code>public static int classSize( final Resource klass ) { return klass.getModel().listSubjectsWithProperty( RDFS.subClassOf, klass ).toList().size(); } public static double pathSize( final List<Resource> path ) { int prevSize = classSize( path.get( 0 )); double pathSum = prevSize; for ( int i = 1; i < path.size(); i++ ) { int currSize = classSize( path.get( i )); double linkWeight = currSize < prevSize ? 0.5 : 1.0; pathSum += linkWeight + currSize; prevSize = currSize; } return pathSum; } </code></pre> <p>It's not exactly clear to me what it is that you're trying to do, but it sounds like you're trying to adjust the <code>currSize</code> in <code>pathSize</code> for certain classes (i.e., the value of returned by <code>path.get( i )</code>, but that you're having trouble comparing whether or not the class is one of the classes for which this should happen. If I'm understanding correctly, you can do something like this:</p> <pre class="lang-java prettyprint-override"><code>private static Resource specialClass = ResourceFactory.createResource( "http://.../specialClass" ); public static double pathSize( final List<Resource> path ) { // ... for ( int i = 1; i < path.size(); i++ ) { final Resource klass = path.get( i ); int currSize = classSize( klass ); if ( specialClass.equals( klass ) ) { // When klass is specialClass currSize = ...; // something different // do the additional modification } // ... } // ... } </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.
