The class itself is also made <code>final</code> by default, because immutability is not something that can be forced onto a subclass. Like <code>@Data</code>, useful <code>toString()</code>, <code>equals()</code> and <code>hashCode()</code> methods are also generated, each field gets a getter method, and a constructor that covers every + argument (except <code>final</code> fields that are initialized in the field declaration) is also generated. + </p><p> + In practice, <code>@Value</code> is shorthand for: <code>final @ToString @EqualsAndHashCode @AllArgsConstructor @FieldDefaults(makeFinal = true, level = AccessLevel.PRIVATE) @Getter</code>. + </p><p> + It is possible to override the final-by-default and private-by-default behaviour using either an explicit access level on a field, or by using the <code>@NonFinal</code> or <code>@PackagePrivate</code> annotations.<br /> + It is possible to override any default behaviour for any of the 'parts' that make up <code>@Value</code> by explicitly using that annotation. + </p> + </div> + <div class="snippets"> + <div class="pre"> + <h3>With Lombok</h3> + <div class="snippet">@HTML_PRE@</div> + </div> + <div class="sep"></div> + <div class="post"> + <h3>Vanilla Java</h3> + <div class="snippet">@HTML_POST@</div> + </div> + </div> + <div style="clear: left;"></div> + <div class="overview"> + <h3>Small print</h3><div class="smallprint"> + <p> + Look for the documentation on the 'parts' of <code>@Value</code>: <a href="ToString.html"><code>@ToString</code></a>, <a href="EqualsAndHashCode.html"><code>@EqualsAndHashCode</code></a>, <a href="Constructor.html"><code>@AllArgsConstructor</code></a>, <a href="experimental/FieldDefaults.html"><code>@FieldDefaults</code></a>, and <a href="GetterSetter.html"><code>@Getter</code></a>. + </p><p> + For classes with generics, it's useful to have a static method which serves as a constructor, because inference of generic parameters via static methods works in java6 and avoids having to use the diamond operator. While you can force this by applying an explicit <code>@AllArgsConstructor(staticConstructor="of")</code> annotation, there's also the <code>@Value(staticConstructor="of")</code> feature, which will make the generated all-arguments constructor private, and generates a public static method named <code>of</code> which is a wrapper around this private constructor. + </p><p> + <code>@Value</code> was an experimental feature from v0.11.4 to v0.11.9 (as <code>@lombok.experimental.Value</code>). It has since been moved into the core package. The old annotation is still + around (and is an alias). It will eventually be removed in a future version, though. + </p><p> + It is not possible to use <code>@FieldDefaults</code> to 'undo' the private-by-default and final-by-default aspect of fields in the annotated class.
