In the following example, 108 109 <pre style="code"> 110 @GwtCompatible 111 class Lists { 112 ... 113 @GwtCompatible(serializable = true) 114 static <E> List<E> newArrayList(E... elements) { 115 ... 116 } 117 } 118 </pre> 119 The return value of <code>Lists.newArrayList(E[])</code> has GWT 120 serializable type. It is also useful in specifying contracts of interface 121 methods. In the following example, 122 123 <pre style="code"> 124 @GwtCompatible 125 interface ListFactory { 126 ... 127 @GwtCompatible(serializable = true) 128 <E> List<E> newArrayList(E... elements); 129 } 130 </pre> 131 The <code>newArrayList(E[])</code> method of all implementations of <code>ListFactory</code> is expected to return a value with a GWT serializable type. 132 133 <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. 134<P> 135 136<P> 137<DL> 138<DT><B>Author:</B></DT> 139 <DD>Charles Fry, Hayward Chan</DD> 140</DL> 141<HR> 142 143<P> 144<!-- =========== ANNOTATION TYPE OPTIONAL MEMBER SUMMARY =========== --> 145 146<A NAME="annotation_type_optional_element_summary"><!-- --></A> 147<TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""> 148<TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"> 149<TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"> 150<B>Optional Element Summary</B></FONT></TH> 151</TR> 152<TR BGCOLOR="white" CLASS="TableRowColor"> 153<TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"> 154<CODE> boolean</CODE></FONT></TD> 155<TD><CODE><B><A HREF="../../../../com/google/common/annotations/GwtCompatible.html#emulated()">emulated</A></B></CODE> 156 157<BR> 158 When <code>true</code>, the annotated type is emulated in GWT.</TD> 159</TR> 160<TR BGCOLOR="white" CLASS="TableRowColor"> 161<TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"> 162<CODE> boolean</CODE></FONT></TD> 163<TD><CODE><B><A HREF="../../../../com/google/common/annotations/GwtCompatible.html#serializable()">serializable</A></B></CODE> 164 165<BR> 166 When <code>true</code>, the annotated type or the type of the method return 167 value is GWT serializable.</TD> 168</TR> 169</TABLE> 170 171<P> 172<A NAME="serializable()"><!-- --></A><H3> 173serializable</H3> 174<PRE> 175public abstract boolean <B>serializable</B></PRE> 176<DL> 177<DD>When <code>true</code>, the annotated type or the type of the method return 178 value is GWT serializable. 179<P> 180<DD><DL> 181</DL> 182</DD> 183<DD><DL> 184<DT><B>See Also:</B><DD><a href="http://code.google.com/docreader/#p=google-web-toolkit-doc-1-5&t=DevGuideSerializableTypes"> 185 Documentation about GWT serialization</a></DL> 186<DL> 187<DT><B>Default:</B><DD>false</DD> 188</DL> 189</DL> 190<HR> 191 192<A NAME="emulated()"><!-- --></A><H3> 193emulated</H3> 194<PRE> 195public abstract boolean <B>emulated</B></PRE> 196<DL> 197<DD>When <code>true</code>, the annotated type is emulated in GWT.
