A scope annotation applies to a class + containing an injectable constructor and governs how the injector reuses + instances of the type. By default, if no scope annotation is present, the + injector creates an instance (by injecting the type's constructor), uses + the instance for one injection, and then forgets it. If a scope annotation + is present, the injector may retain the instance for possible reuse in a + later injection. If multiple threads can access a scoped instance, its + implementation should be thread safe. The implementation of the scope + itself is left up to the injector. + + <p>In the following example, the scope annotation <code>@Singleton</code> ensures + that we only have one Log instance: + + <pre> + @Singleton + class Log { + void log(String message) { ... } + }</pre> + + <p>The injector generates an error if it encounters more than one scope + annotation on the same class or a scope annotation it doesn't support. + + <p>A scope annotation: + <ul> + <li>is annotated with <code>@Scope</code>, <code>@Retention(RUNTIME)</code>, + and typically <code>@Documented</code>.</li> + <li>should not have attributes.</li> + <li>is typically not <code>@Inherited</code>, so scoping is orthogonal to + implementation inheritance.</li> + <li>may have restricted usage if annotated with <code>@Target</code>. While + this specification covers applying scopes to classes only, some + injector configurations might use scope annotations + in other places (on factory method results for example).</li> + </ul> + + <p>For example: + + <pre> + @java.lang.annotation.Documented + @java.lang.annotation.Retention(RUNTIME) + @javax.inject.Scope + public @interface RequestScoped {}</pre> + + <p>Annotating scope annotations with <code>@Scope</code> helps the injector + detect the case where a programmer used the scope annotation on a class but + forgot to configure the scope in the injector. A conservative injector + would generate an error rather than not apply a scope. +<P> + +<P> +<DL> +<DT><B>See Also:</B><DD><A HREF="../../javax/inject/Singleton.html" title="annotation in javax.inject"><CODE>@Singleton</CODE></A></DL> + +<P> + +<P> +<!-- ========= END OF CLASS DATA ========= --> +<HR> + + +<!-- ======= START OF BOTTOM NAVBAR ====== --> +<A NAME="navbar_bottom"><!-- --></A> +<A HREF="#skip-navbar_bottom" title="Skip navigation links"></A> +<TABLE BORDER="0" WIDTH="100%" CELLPADDING="1" CELLSPACING="0" SUMMARY=""> +<TR> +<TD COLSPAN=2 BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> +<A NAME="navbar_bottom_firstrow"><!-- --></A> +<TABLE BORDER="0" CELLPADDING="0" CELLSPACING="3" SUMMARY=""> + <TR ALIGN="center" VALIGN="top"> + <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../javax/inject/package-summary.html"><FONT CLASS="NavBarFont1"><B>Package</B></FONT></A> </TD> + <TD BGCOLOR="#FFFFFF" CLASS="NavBarCell1Rev"> <FONT CLASS="NavBarFont1Rev"><B>Class</B></FONT> </TD> + <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="package-tree.html"><FONT CLASS="NavBarFont1"><B>Tree</B></FONT></A> </TD> + <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../deprecated-list.html"><FONT CLASS="NavBarFont1"><B>Deprecated</B></FONT></A> </TD> + <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../index-all.html"><FONT CLASS="NavBarFont1"><B>Index</B></FONT></A> </TD> + <TD BGCOLOR="#EEEEFF" CLASS="NavBarCell1"> <A HREF="../../help-doc.html"><FONT CLASS="NavBarFont1"><B>Help</B></FONT></A> </TD> + </TR> +</TABLE> +</TD> +<TD ALIGN="right" VALIGN="top" ROWSPAN=3><EM> +</EM> +</TD> +</TR> + +<TR> +<TD BGCOLOR="white" CLASS="NavBarCell2"><FONT SIZE="-2"> + <A HREF="../../javax/inject/Qualifier.html" title="annotation in javax.inject"><B>PREV CLASS</B></A> + <A HREF="../../javax/inject/Singleton.html" title="annotation in javax.inject"><B>NEXT CLASS</B></A></FONT></TD> +<TD BGCOLOR="white" CLASS="NavBarCell2"><FONT SIZE="-2"> + <A HREF="../../index.html?javax/inject/Scope.html" target="_top"><B>FRAMES</B></A> + <A HREF="Scope.html" target="_top"><B>NO FRAMES</B></A> + <SCRIPT type="text/javascript"> + <!-- + if(window==top) { + document.writeln('<A HREF="../../allclasses-noframe.html"><B>All Classes</B></A>'); + } + //--> +</SCRIPT> +<NOSCRIPT> + <A HREF="../../allclasses-noframe.html"><B>All Classes</B></A> +</NOSCRIPT> + + +</FONT></TD> +</TR> +<TR> +<TD VALIGN="top" CLASS="NavBarCell3"><FONT SIZE="-2"> + SUMMARY: REQUIRED | OPTIONAL</FONT></TD> +<TD VALIGN="top" CLASS="NavBarCell3"><FONT SIZE="-2"> +DETAIL: ELEMENT</FONT></TD> +</TR> +</TABLE> +<A NAME="skip-navbar_bottom"></A> +<!-- ======== END OF BOTTOM NAVBAR ======= --> + +<HR> +<font size='-1'>Copyright (C) 2009 <a href='http://code.google.com/p/atinject/'>The JSR-330 Expert Group</a>.
