You might be interested in op4j [http://www.op4j.org], a utility library for improving code readability and quality in Java based on the “Fluent Interface” concept.

how can you handle the modification of an instance with the fluent interfaces?

I have added a new method called “modify”, so that it is possible
to modify existing instances like:
person.modify().age(3).firstName(“Uwe”).lastName(“Langjahr”).active(false).age(109);

The method is implemented:
public PersonFluentInterface modify () {
return FluentInterface.create(this, PersonFluentInterface.class);
}

It works, but my problem is, that I’m not familiar with the reflection interface. Can you please
validate, that this implementation is correct (no unnecessary new instance are created etc.)

I wrote created an opensource library for creating Builders with fluent interface based on your idea in this post.
I think I put the propert credits to you, if there are any problem let me know.

I have also extended the builder to manage object lists.
For example if Person has a property named ‘lovedThings’ of type List with the library I wrote you can write:

Person person = Person.builder()
.withFirstName(“John”)
.withLovedThings(“pizza”, “soccer”, “jogging”)
.build();

The library can be found at http://www.andreafrancia.it/articoli/fluent-builder

# public static PersonFluentInterface with(Person person) {
# return FluentInterface.create(
# person, PersonFluentInterface.class);
# }

might be a good addition. Because sometimes the instance is already available, but you still want to populate it fluently.

Good idea.liked the implementation.BTW what’s the small bug?

Thanks

Perhaps the presentation will help me get rid of the suppress warning annotation.
