    <p>I have a service method that needs to process an incoming object: (by the way, this is pseudo code)</p> <pre><code>public class IncomingParentObject { public Collection&lt;IncomingChildOject&gt; childObjects; } public Class IncmoingChildObject { public String name; } </code></pre> <p>I have a "registry" of "clients" that care about a subset of the incoming child objects. At the point of registration we only know about the "name". The client object encapsulates details for the transport layer to forward information to.</p> <pre><code>public class Registry { // String represents the name in the child object public Map&lt;String, Set&lt;Client&gt;&gt; clients; } </code></pre> <p>Right now the service class is something along the lines of this:</p> <pre><code>public void processIncmoingParentObject(IncomingParentObject parentObject) { for (IncmoingChildObject childObject : parentObject.childObjects) { Set&lt;Client&gt; clients = registry.clients.get(childObject.name); for (Client client : clients) { this.transportLayer.transportChildObject(childObject, client); } } } </code></pre> <p>This results in several calls to the transportLayer (which may be expensive or timely). I want to reduce this to basically one transport per client of a subset of ChildObjects. </p> <pre><code>transportLayer.transport(Client client, Set&lt;IncmoingChildObject&gt; childObjects); </code></pre> <p>What would an effiecent manor be to scan through the parents children to determine a subset of children to send to a client. </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
