------------------------------------------
+1 as well. Seems to fit well with Dataset to provide a fluent API.
>Can someone confirm whether this is binary compatible?
I don't think it is binary compatible.

Changing the result type of a method, or replacing a result type with void, or
replacing void with a result type, has the combined effect of deleting the old
method and adding a new method with the new result type or newly void result
(see ยง13.4.12).

And from
http://docs.oracle.com/javase/specs/jls/se8/html/jls-13.html#jls-13.4.12:
{quote}
Deleting a method or constructor from a class may break compatibility with any
pre-existing binary that referenced this method or constructor; a
NoSuchMethodError may be thrown when such a reference from a pre-existing
binary is linked. Such an error will occur only if no method with a matching
signature and return type is declared in a superclass.

> Key: JENA-1389
> URL: https://issues.apache.org/jira/browse/JENA-1389
> Project: Apache Jena
> Issue Type: Improvement
> Components: ARQ
> Affects Versions: Jena 3.4.0
> Reporter: Adam Jacobs
> Priority: Trivial
> Labels: easytask
>
> Allow method chaining from the org.apache.jena.query.Dataset interface by
> returning `this` rather than `void` from the following methods.
> # setDefaultModel
> # addNamedModel
> # removeNamedModel
> # replaceNamedModel
> Allowing method chaining would align with the behavior of the add and remove
> methods in org.apache.jena.rdf.model.Model.
