Body
While this is not yet valid for Java 7 and below, I believe that we should look to the future and at least recognize <a href="http://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html" rel="nofollow">the changes</a> to come in new versions such as Java 8. Namely, this new version brings <a href="http://www.lambdafaq.org/what-is-a-lambda-expression/" rel="nofollow">lambdas</a> and method references to Java (along with <a href="http://lambdadoc.net/api/" rel="nofollow">new APIs</a>, which are another valid solution to this problem. While they still require an interface no new objects are created, and extra classfiles need not pollute output directories due to different handling by the JVM. Both flavors(lambda and method reference) require an interface available with a single method whose signature is used: <pre><code>public interface NewVersionTest{ String returnAString(Object oIn, String str); } </code></pre> Names of methods will not matter from here on. Where a lambda is accepted, a method reference is as well. For example, to use our signature here: <pre><code>public static void printOutput(NewVersionTest t, Object o, String s){ System.out.println(t.returnAString(o, s)); } </code></pre> This is just a simple interface invocation, up until the lambda1 gets passed: <pre><code>public static void main(String[] args){ printOutput( (Object oIn, String sIn) -> { System.out.println("Lambda reached!"); return "lambda return"; } ); } </code></pre> This will output: <pre><code>Lambda reached! lambda return </code></pre> Method references are similar. Given: <pre><code>public class HelperClass{ public static String testOtherSig(Object o, String s){ return "real static method"; } } </code></pre> and main: <pre><code>public static void main(String[] args){ printOutput(HelperClass::testOtherSig); } </code></pre> the output would be <code>real static method</code>. <a href="http://docs.oracle.com/javase/tutorial/java/javaOO/methodreferences.html" rel="nofollow">Method references can be static, instance, non-static with arbitrary instances, and even constructors</a>. For the constructor something akin to <code>ClassName::new</code> would be used. 1 This is not considered a lambda by some, as it has side effects. It does illustrate, however, the use of one in a more straightforward-to-visualize fashion.

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.
