Hi, I am currently finishing the work of someone else which also
includes a QueryEngine and a Rewrite of queries (basicly adding a
FILTER-statement). The adding-part works fine and does exactly as
expected. When I rewrite the query SELECT ?x ?y ?z WHERE {?x ?y ?z} I
get SELECT ?x ?y ?z WHERE {?x ?y ?z . FILTER restOfFilter} However,
when I take this query and send the same request for rewriting I get
an alteration of the FILTER that is in the original Query send. Here
is the beginning of the original Filter (first one) and the correct
FILTER, that has been added :
FILTER ( ( ( isLiteral(?x) || ( ( ( ! isBlank(?x) )&& isIRI(?x) )
FILTER ( ( ( isLiteral(?x) || ( ( ! isBlank(?x) )&& ( isIRI(?x)
But it should really be the same FILTER statement twice. If tracked
down the problem to the line:
_query = QueryFactory.parse(_query, _queryQurrent, null, null);
This is, where the alteration occurs. Another weird thing is, that it
does not occur with other queries, that went through the same
process.
I have no clue, why this happens, so I hope someone can help me with
this. Thanks in advance. Sincerely Christian Pechhold
Without seeing the rest of the query, I can only guess but is the code
reading and updating the same Query object at the same time in some way?
It might be that parsing/printing has a bug but without a complete,
minimal example, I can't investigate.
What's the version number of ARQ?
