Examples of org.exist.xmldb.XPathQueryServiceImpl.beginProtected()

org.exist.xmldb.XPathQueryServiceImpl.beginProtected()
Execute all following queries in a protected environment. Acquire a write lock on all resources in the current collection (i.e. the one from which this service was obtained) before executing the query. If a query spans multiple collections, call beginProtected on the outer collection which contains all the other collections. It is thus guaranteed that documents referenced by the query or the result set are not modified by other threads until {@link #endProtected} is called.

            .getCollection("xmldb:exist://" + collection, "admin", null);
                if (testCollection == null)
                    return;
                XPathQueryServiceImpl service = (XPathQueryServiceImpl) testCollection
            .getService("XQueryService", "1.0");
        service.beginProtected();
        try {
          ResourceSet result = service.query(query);
          System.out.println("Result: " + result.getSize());

          service.endProtected();
