@Target(value={FIELD,TYPE})
@Retention(value=SOURCE)
public @interface Wither

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).

Example:

     private @Wither final int foo;
 

will generate:

     public SELF_TYPE withFoo(int foo) {
         return this.foo == foo ? this : new SELF_TYPE(otherField1, otherField2, foo);
     }
 

If any method named withFoo (case insensitive) exists, regardless of return type or parameters, no method is generated, and instead a compiler warning is emitted.

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 Wither annotation have the annotation.
