    <p>I'm writing a util to generate interface for class using Apache Velocity. Currently it uses the following dtos:</p> <pre><code>public class ClassDescriptor { private String name; private List&lt;MethodDescriptor&gt; methods; // getters/setters } public class MethodDescriptor { private String name; private String returnType; private List&lt;ParamDescriptor&gt; parameters; // getters/setters } public class ParamDescriptor { public String name; public String type; public List&lt;String&gt; generics; // getters/setters } </code></pre> <p>Here is the code used at the moment:</p> <pre><code>final Class&lt;?&gt; clazz; final ClassDescriptor classDescriptor = new ClassDescriptor(); final List&lt;MethodDescriptor&gt; methodDescriptors = new ArrayList&lt;MethodDescriptor&gt;(); for (Method method : clazz.getDeclaredMethods()) { final MethodDescriptor methodDescriptor = new MethodDescriptor(); final Paranamer paranamer = new AdaptiveParanamer(); final String[] parameterNames = paranamer.lookupParameterNames(method, false); final List&lt;ParamDescriptor&gt; paramDescriptors = new ArrayList&lt;ParamDescriptor&gt;(); for (int i = 0; i &lt; method.getParameterTypes().length; i++) { final ParamDescriptor paramDescriptor = new ParamDescriptor(); paramDescriptor.setName(parameterNames[i]); paramDescriptors.add(paramDescriptor); paramDescriptor.setType(method.getGenericParameterTypes()[i].toString().replace("class ", "")); } methodDescriptor.setParameters(paramDescriptors); methodDescriptor.setName(method.getName()); methodDescriptor.setReturnType(method.getGenericReturnType().toString()); methodDescriptors.add(methodDescriptor); } classDescriptor.setMethods(methodDescriptors); classDescriptor.setName(simpleName); </code></pre> <p>The ????? should contain code to get a list of generics for the parameter and that is the problem, I still can't find a way to do that. I'm using the following test class:</p> <pre><code>public class TestDto { public void test(Map&lt;Double, Integer&gt; test) { } } </code></pre> <p>How can I get this information? I've already tried <code>ParameterizedType</code> with no luck. </p> <p><strong>Update:</strong> the code above is now working.</p>

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.
