// Define abstract value type using interface, abstract class or annotation
@ Value . Immutable
public interface ValueObject extends WithValueObject {
// WithValueObject is not yet generated, We extend With* to inherit `with*` method signatures
String name ();
List < Integer > counts ();
Optional < String > description ();
class Builder extends ImmutableValueObject . Builder {}
// ImmutableValueObject.Builder will be generated and
// our builder will inherit and reexport methods as its own.
// Static nested Builder will inherit all the public method
// signatures of ImmutableValueObject.Builder
}
// Use generated immutable implementation and builder
ValueObject v =
new ValueObject . Builder ()
. name ( "Nameless" )
. description ( "present" )
. addCounts ( 1 )
. addCounts ( 2 )
. build ();
v = v . withName ( "Doe" );
//fetch values via accessors
List < Integer > counts = v . counts ();
Optional < String > description = v . description ();
В этом случае ImmutableValueObject не будет использоваться вне сгенерированного типа. Подробнее об этом и других стилях генерации см. здесь.
