Body
<p>Currently I am working on a Java agent to assemble memory stats. With the help of the <a href="http://http://java.sun.com/javase/6/docs/api/java/lang/instrument/Instrumentation.html" rel="nofollow noreferrer">instrumentation API</a> I can get a hold of the classes (and manipulate them). With plain Java I can get an estimate of the resources used for each object. So far, so good.</p> <p>The question I am faced with right now is "how to get a hold of every Object instance of a specific class". I can do byte code manipulation in order to get a hold of the object instance, but I was hoping there is another API I am not aware of, helping me to accomplish my goal without such a rather heavy intrusive step. At the end, the performance impact should be kept to a minimum. Any ideas?</p>

Guidance

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.
