fluent setters #197

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
(mentioned in the Google Groups a few times but doesn't seem to be in the 
issues list)

plain Java:

class Foo {
   private int x;
   private String s;

   public Foo setX(int x) { this.x = x; }
   public Foo setS(String s) { this.s = s; }
}

use case:

Foo foo = new Foo().setX(3).setS("something");

If this is part of the @Builder implementation 
(http://code.google.com/p/projectlombok/issues/detail?id=16), and the fluent 
setters are easier to implement than the @Builder, please release this one 
first.

(this should have been an enhancement, not a defect, sorry)

Darn -- I just noticed issue 15. This is a duplicate.

But again, if it's easier to implement than the full @Builder, please release 
this first.

Please reopen.

There is a difference between Builder and Fluent; please add a @Fluent along 
the lines of this:

http://martinfowler.com/bliki/FluentInterface.html

The main problem with builder is the build() method. I just want to make a 
@Data class with chainable set() methods, not a Builder. The reason for this is 
that the Data class gets passed up several levels and is manipulated along the 
way. I'd rather not pass a builder but instead a DTO with fluent setters.

@Accessors(fluent=true) should do the trick for you.
