<h1>@FieldDefaults</h1>
<div class="byline">New default field modifiers for the 21st century.</div>
<div class="since">
<h3>Since</h3>
<p>
@FieldDefaults was introduced as experimental feature in lombok v0.11.4.
</p>
</div>
<div class="experimental">
<h3>Experimental</h3>
<p>
Experimental because:
<ul>
<li>New feature; unsure if this busts enough boilerplate</li>
<li>Would be nice if you could stick this on the package-info.java package to set the default for all classes in that package</li>
<li>Part of the work on @Value, which is experimental</li>
</ul>
Current status: <em>positive</em> - Currently we feel this feature may move out of experimental status with no or minor changes soon.
</div>
<div class="overview">
<h3>Overview</h3>
<p>
The <code>@FieldDefaults</code> annotation can add an access modifier (<code>public</code>, <code>private</code>, or <code>protected</code>)
to each field in the annotated class or enum. It can also add <code>final</code> to each field in the annotated class or enum.
</p>
</p><p>
To add <code>final</code> to each field, use <code>@FieldDefaults(makeFinal=true)</code>. Any non-final field which must remain nonfinal
can be annotated with <code>@NonFinal</code> (also in the <code>lombok.experimental</code> package).
</p><p>
To add an access modifier to each field, use <code>@FieldDefaults(level=AccessLevel.PRIVATE)</code>. Any field that does not already have an
access modifier (i.e. any field that looks like package private access) is changed to have the appropriate access modifier. Any package private
field which must remain package private can be annotated with <code>@PackagePrivate</code> (also in the <code>lombok.experimental</code> package).

<dl>
<dt><code>lombok.fieldDefaults.flagUsage</code> = [<code>warning</code> | <code>error</code>] (default: not set)</dt>
<dd>Lombok will flag any usage of <code>@FieldDefaults</code> as a warning or error if configured.</dd>

<h3>Small print</h3><div class="smallprint">
<p>
Like other lombok handlers that touch fields, any field whose name starts with a dollar (<code>$</code>) symbol is skipped entirely.
Such a field will not be modified at all.
