<@f.scaffold title="@Getter and @Setter" logline="Never write <code>public int getFoo() {return foo;}</code> again.">
<@f.overview>
<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.
</p><p>
To put annotations on the generated method, you can use <code>onMethod=@__({@AnnotationsHere})</code>; to put annotations on the only parameter of a generated setter method, you can use <code>onParam=@__({@AnnotationsHere})</code>. Be careful though! This is an experimental feature. For more details see the documentation on the <a href="/features/experimental/onX">onX</a> feature.
</p><p>
<em>NEW in lombok v1.12.0:</em> javadoc on the field will now be copied to generated getters and setters. Normally, all text is copied, and <code>@return</code> is <em>moved</em> to the getter, whilst <code>@param</code> lines are <em>moved</em> to the setter. Moved means: Deleted from the field's javadoc. It is also possible to define unique text for each getter/setter. To do that, you create a 'section' named <code>GETTER</code> and/or <code>SETTER</code>. A section is a line in your javadoc containing 2 or more dashes, then the text 'GETTER' or 'SETTER', followed by 2 or more dashes, and nothing else on the line. If you use sections, <code>@return</code> and <code>@param</code> stripping for that section is no longer done (move the <code>@return</code> or <code>@param</code> line into the section).

<@f.confKeys>
<dt>
<code>lombok.accessors.chain</code> = [<code>true</code> | <code>false</code>] (default: false)
</dt><dd>
If set to <code>true</code>, generated setters will return <code>this</code> (instead of <code>void</code>). An explicitly configured <code>chain</code> parameter of an <a href="/features/experimental/Accessors"><code>@Accessors</code></a> annotation takes precedence over this setting.
</dd><dt>
<code>lombok.accessors.fluent</code> = [<code>true</code> | <code>false</code>] (default: false)
</dt><dd>
If set to <code>true</code>, generated getters and setters will not be prefixed with the bean-standard '<code>get</code>, <code>is</code> or <code>set</code>; instead, the methods will use the same name as the field (minus prefixes). An explicitly configured <code>chain</code> parameter of an <a href="/features/experimental/Accessors"><code>@Accessors</code></a> annotation takes precedence over this setting.
</dd><dt>
<code>lombok.accessors.prefix</code> += <em>a field prefix</em> (default: empty list)
</dt><dd>
This is a list property; entries can be added with the <code>+=</code> operator. Inherited prefixes from parent config files can be removed with the <code>-=</code> operator. Lombok will strip any matching field prefix from the name of a field in order to determine the name of the getter/setter to generate. For example, if <code>m</code> is one of the prefixes listed in this setting, then a field named <code>mFoobar</code> will result in a getter named <code>getFoobar()</code>, not <code>getMFoobar()</code>. An explicitly configured <code>prefix</code> parameter of an <a href="/features/experimental/Accessors"><code>@Accessors</code></a> annotation takes precedence over this setting.
</dd><dt>
<code>lombok.getter.noIsPrefix</code> = [<code>true</code> | <code>false</code>] (default: false)
</dt><dd>
If set to <code>true</code>, getters generated for <code>boolean</code> fields will use the <code>get</code> prefix instead of the default<code>is</code> prefix, and any generated code that calls getters, such as <code>@ToString</code>, will also use <code>get</code> instead of <code>is</code>
</dd><dt>
<code>lombok.setter.flagUsage</code> = [<code>warning</code> | <code>error</code>] (default: not set)
</dt><dd>
Lombok will flag any usage of <code>@Setter</code> as a warning or error if configured.
</dd><dt>
<code>lombok.getter.flagUsage</code> = [<code>warning</code> | <code>error</code>] (default: not set)
</dt><dd>
Lombok will flag any usage of <code>@Getter</code> as a warning or error if configured.
</dd><dt>
<code>lombok.copyableAnnotations</code> = [<em>A list of fully qualified types</em>] (default: empty list)
</dt><dd>
Lombok will copy any of these annotations from the field to the setter parameter, and to the getter method. Note that lombok ships with a bunch of annotations 'out of the box' which are known to be copyable: All popular nullable/nonnull annotations.
</dd>
</@f.confKeys>
<@f.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 (case insensitive) and same parameter count. For example, <code>getFoo()</code> will not be generated if there's already a method <code>getFoo(String... 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. Varargs count as 0 to N parameters. You can mark any method with <code>@lombok.experimental.Tolerate</code> to hide them from lombok.
</p><p>
For <code>boolean</code> fields that start with <code>is</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>
A number of annotations from popular libraries that indicate non-nullness, such as <code>javax.annotation.Nonnull</code>, if present on the field, result in an explicit null check in the generated setter.
</p><p>
Various well-known annotations about nullability, such as <code>org.eclipse.jdt.annotation.NonNull</code>, are automatically copied over to the right place (method for getters, parameter for setters). You can specify additional annotations that should always be copied via lombok <a href="/features/configuration">configuration key</a> <code>lombok.copyableAnnotations</code>.
</p><p>
You can annotate a class with a <code>@Getter</code> or <code>@Setter</code> annotation. Doing so is equivalent to annotating all non-static fields in that class with that annotation. <code>@Getter</code>/<code>@Setter</code> annotations on fields take precedence over the ones on classes.
</p><p>
Using the <code>AccessLevel.NONE</code> access level simply generates nothing. It's useful only in combination with <a href="/features/Data"><code>@Data</code></a> or a class-wide <code>@Getter</code> or <code>@Setter</code>.
</p><p>
<code>@Getter</code> can also be used on enums. <code>@Setter</code> can't, not for a technical reason, but for a pragmatic one: Setters on enums are an extremely bad idea.
