/**
* Put on any field to make lombok build a 'wither' - a withX method which produces a clone of this object (except for 1 field which gets a new value).
* <p>
* Complete documentation is found at <a href="http://projectlombok.org/features/experimental/Wither.html">the project lombok features page for @Wither</a>.
* <p>
* Even though it is not listed, this annotation also has the {@code onParam} and {@code onMethod} parameter. See the full documentation for more details.
* <p>
* Example:
* <pre>
* private @Wither final int foo;
* </pre>
*
* will generate:
*
* <pre>
* public SELF_TYPE withFoo(int foo) {
* return this.foo == foo ? this : new SELF_TYPE(otherField1, otherField2, foo);
* }
* </pre>
* <p>
* This annotation can also be applied to a class, in which case it'll be as if all non-static fields that don't already have
* a {@code Wither} annotation have the annotation.
