public @interface <span class="memberNameLabel">XmlList</span></pre>
<div class="block">Used to map a property to a list simple type.
<p><b>Usage</b> </p>
<p>
The <code>@XmlList</code> annotation can be used with the
following program elements:
<ul>
<li> JavaBean property </li>
<li> field </li>
</ul>
<p>
When a collection property is annotated just with @XmlElement,
each item in the collection will be wrapped by an element.
For example,
<pre>
&#64;XmlRootElement
class Foo {
&#64;XmlElement
List&lt;String&gt; data;
}
</pre>
would produce XML like this:
<pre><code>
&lt;foo&gt;
&lt;data&gt;abc&lt;/data&gt;
&lt;data&gt;def&lt;/data&gt;
&lt;/foo&gt;
</code></pre>
&#64;XmlList annotation, on the other hand, allows multiple values to be
represented as whitespace-separated tokens in a single element. For example,
<pre>
&#64;XmlRootElement
class Foo {
&#64;XmlElement
&#64;XmlList
List&lt;String&gt; data;
}
</pre>
the above code will produce XML like this:
<pre><code>
&lt;foo&gt;
&lt;data&gt;abc def&lt;/data&gt;
&lt;/foo&gt;
</code></pre>
<p>This annotation can be used with the following annotations:
<a href="XmlElement.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlElement</code></a>,
<a href="XmlAttribute.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlAttribute</code></a>,
<a href="XmlValue.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlValue</code></a>,
<a href="XmlIDREF.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlIDREF</code></a>.
<ul>
<li> The use of <code>@XmlList</code> with <a href="XmlValue.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlValue</code></a> while
allowed, is redundant since <a href="XmlList.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlList</code></a> maps a
collection type to a simple schema type that derives by
list just as <a href="XmlValue.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlValue</code></a> would. </li>
<li> The use of <code>@XmlList</code> with <a href="XmlAttribute.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlAttribute</code></a> while
allowed, is redundant since <a href="XmlList.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlList</code></a> maps a
collection type to a simple schema type that derives by
list just as <a href="XmlAttribute.html" title="annotation in jakarta.xml.bind.annotation"><code>XmlAttribute</code></a> would. </li>
