</PRE>
<P>
The presence of this annotation on a type indicates that the type may be
used with the
<a href="http://code.google.com/webtoolkit/">Google Web Toolkit</a> (GWT).
When applied to a method, the return type of the method is GWT compatible.
It's useful to indicate that an instance created by factory methods has a GWT
serializable type. In the following example,
<pre style="code">
@GwtCompatible
class Lists {
...
@GwtCompatible(serializable = true)
static &lt;E> List&lt;E> newArrayList(E... elements) {
...
}
}
</pre>
The return value of <code>Lists.newArrayList(E[])</code> has GWT
serializable type. It is also useful in specifying contracts of interface
methods. In the following example,
<pre style="code">
@GwtCompatible
interface ListFactory {
...
@GwtCompatible(serializable = true)
&lt;E> List&lt;E> newArrayList(E... elements);
}
</pre>
The <code>newArrayList(E[])</code> method of all implementations of <code>ListFactory</code> is expected to return a value with a GWT serializable type.
<p>Note that a <code>GwtCompatible</code> type may have some <A HREF="../../../../com/google/common/annotations/GwtIncompatible.html" title="annotation in com.google.common.annotations"><CODE>GwtIncompatible</CODE></A> methods.
