Annotation Type Wither

@Target({FIELD,TYPE}) @Retention(SOURCE) public @interface Wither
Deprecated.
With has been promoted to the main package, so use that one instead.
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).

Complete documentation is found at the project lombok features page for @Wither.

Even though it is not listed, this annotation also has the onParam and onMethod parameter. See the full documentation for more details.

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);
     }

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.
