Examples of prepareBooleanQuery()

com.bigdata.rdf.sail.BigdataSailRepositoryConnection.prepareBooleanQuery()
org.openrdf.repository.RepositoryConnection.prepareBooleanQuery()
Prepares true/false queries. In case the query contains relative URIs that need to be resolved against an external base URI, one should use {@link #prepareBooleanQuery(QueryLanguage,String,String)}instead. @param ql The query language in which the query is formulated. @param query The query string. @throws IllegalArgumentException If the supplied query is not a boolean query. @throws MalformedQueryException If the supplied query is malformed. @throws UnsupportedQueryLanguageException If the supplied query language is not supported.

        // test snapshot connection for date3 (i.e. after first update)
        RepositoryConnection snapshot2 = repository.getSnapshot(date3);

        BooleanQuery query2_1 = snapshot2.prepareBooleanQuery(QueryLanguage.SPARQL, "ASK { <http://marmotta.incubator.apache.org/testing/ns1/R1> ?p ?o }");
