It works. Now I understand, that I just did not find the right tools (in this
case {{ExprFactory}}).
That means, this issue is somehow obsolete. Sorry for unintended misusing the
issue tracker for something that should be a help request, again.
Unfortunately, I did not find (and I think there isn't) any documentation or
tutorial about the query builders explaining more than the [very
basics|https://jena.apache.org/documentation/extras/querybuilder/index.html].
Also the
[JavaDoc|https://jena.apache.org/documentation/extras/querybuilder/index.html]
(which is to the best of my knowledge nowhere linked on
[https://jena.apache.org/]), is, in my experience, not helpful and makes it
often necessary to look into the code to understand what is needed and maybe
find out how to get it. If I did not miss a comprehensive documentation
somewhere, I think it would be worth, to improve documentation. Even a few
words at the builder classes (mentioning e.g. {{ExprFactory}}) and small
examples at the more complicated methods would help a lot. Should I open a new
issue or transform this issue to cover the documentation topic?

> To enable the inline use of

> generation, I propose to:
> * add constructor {{public ElementTriplesBlock(Triple triple)}}
> * add constructor {{public ElementTriplesBlock(Node s, Node p, Node o)}}

> ** {{addTriple(int index, Triple t)}}
> ** {{addTriplePath(TriplePath path)}}
> ** {{addTriplePath(int index, TriplePath path)}}
