    <p>Suppose I have a simple Java class like this:</p> <pre><code>public class User { String firstName; String lastName; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } } </code></pre> <p>Now, suppose I want to parse the following XML:</p> <pre><code>&lt;user&gt; &lt;firstName&gt;Homer&lt;/firstName&gt; &lt;lastName&gt;Simpson&lt;/lastName&gt; &lt;/user&gt; </code></pre> <p>I can do this with no problems in XStream like so:</p> <pre><code>User homer = (User) xstream.fromXML(xml); </code></pre> <p>Ok, all good so far, but here's my problem.</p> <p>Suppose I have the following XML that I want to parse:</p> <pre><code>&lt;user&gt; &lt;fullName&gt;Homer Simpson&lt;/fullName&gt; &lt;/user&gt; </code></pre> <p>How can I convert this XML into the <strong>same</strong> User object using XStream? </p> <p>I'd like a way to implement some kind of callback so that when XStream parses the fullName field, I can split the string in two and manually set the first name and last name fields on the user object. Is this possible?</p> <p>Note that I'm not asking how to split the string in two (that's the easy part), I want to know how to intercept the XML parsing so XStream doesn't try to reflectively set the fullName field on the User object (which obviously doesn't exist).</p> <p>I looked at the converters that XStream provides but couldn't figure out how to use it for this purpose.</p> <p>Any help would be appreciated.</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.
