extract query patterns

[Miguel Bento Alves]

Hi all, 

In a Sparql query, we can extract the query pattern ( q.getQueryPattern() ). 
For instance, in the sparql command:
        Select ?x ?p ?z where {?x ?p ?y . ?x <eg:p> ?z.}
we can extract:
        { ?x ?p ?y .
          ?x <eg:p> ?z
        } 

Is there anyway to extract as TriplePattern?

Also, we can extract the vars ( PatternVars.vars(qf.getQueryPattern()) ).  Is 
it possible to extract the the non-vars?
