<p>The necessary callbacks (<code>MyCallback</code> class) now has to be registered during the corresponding <code>readEntity(...)</code> call. Therefore we first create a map with the property name as key and the according callback as value. Additional we need to create the <code>ExpandSelectTreeNode</code> based on current element position. Both then have to be set in the <code>EntityProviderWritePropertiesBuilder</code>. </p>
<p>The following code show the few lines we need for extending the read of a car with its expanded manufacturer.</p>
