<h1>@Getter and @Setter</h1>

<div class="overview">
<h3>Overview</h3>
<p>
You can annotate any field with <code>@Getter</code> and/or <code>@Setter</code>, to let lombok generate the default getter/setter automatically.<br />
A default getter simply returns the field, and is named <code>getFoo</code> if the field is called <code>foo</code> (or <code>isFoo</code>
if the field's type is <code>boolean</code>). A default setter is named <code>setFoo</code> if the field is called <code>foo</code>, returns <code>void</code>,
and takes 1 parameter of the same type as the field. It simply sets the field to this value.
</p><p>
The generated getter/setter method will be <code>public</code> unless you explicitly specify an <code>AccessLevel</code>, as shown in the example below.
Legal access levels are <code>PUBLIC</code>, <code>PROTECTED</code>, <code>PACKAGE</code>, and <code>PRIVATE</code>.
</p><p>
You can also put a <code>@Getter</code> and/or <code>@Setter</code> annotation on a class. In that case, it's as if you annotate all the non-static fields in that
class with the annotation.
</p><p>
You can always manually disable getter/setter generation for any field by using the special <code>AccessLevel.NONE</code> access level. This lets you override the
behaviour of a <code>@Getter</code>, <code>@Setter</code> or <code>@Data</code> annotation on a class.

<h3>Small print</h3><div class="smallprint">
<p>
For generating the method names, the first character of the field, if it is a lowercase character, is title-cased, otherwise, it is left unmodified.
Then, get/set/is is prefixed.
</p><p>
No method is generated if any method already exists with the same name, even if the parameter list is different. For example, <code>getFoo()</code>
will not be generated if there's already a method <code>getFoo(int x)</code> even though it is technically possible to make the method. This caveat
exists to prevent confusion. If the generation of a method is skipped for this reason, a warning is emitted instead.
</p><p>
For <code>boolean</code> fields that start with <code>is</code> or <code>has</code> immediately followed by a title-case letter, nothing is prefixed
to generate the getter name.
</p><p>
Any variation on <code>boolean</code> will <em>not</em> result in using the <code>is</code> prefix instead of the <code>get</code> prefix; for example,
returning <code>java.lang.Boolean</code> results in a <code>get</code> prefix, not an <code>is</code> prefix.
</p><p>
Any annotations named <code>@NonNull</code> (case insensitive) on the field are interpreted as: This field must not ever hold
<em>null</em>. Therefore, these annotations result in an explicit null check in the generated setter. Also, these
annotations (as well as any annotation named <code>@Nullable</code> or <code>@CheckForNull</code>) are copied to setter parameter and getter method
</p><p>
Using the <code>AccessLevel.NONE</code> access level simply generates nothing. It's useful only in combination with
<a href="Data.html"><code>@Data</code></a>.
