evaluateTupleQuery
public void evaluateTupleQuery(TupleResultBuilder builder, String xslPath, WorkbenchRequest req, javax.servlet.http.HttpServletResponse resp, CookieHandler cookies, TupleQuery query, boolean writeCookie, boolean paged, int offset, int limit) throws QueryEvaluationException, QueryResultHandlerException Evaluate a tuple query, and create an XML results document. This method completes writing of the response. !paged means use all results.- Parameters:
builder
- response builder helper for generating the XML response to the client, which must not have had start() called on itxslPath
- needed to begin writing response body after writing result count cookiereq
- needed to write result count cookieresp
- needed to write result count cookiecookies
- needed to write result count cookiequery
- the query to be evaluatedwriteCookie
- whether to write the total result count cookiepaged
- whether to display a limited subset- Throws:
QueryResultHandlerException
QueryEvaluationException

evaluateTupleQuery
public void evaluateTupleQuery(TupleResultBuilder builder, TupleQuery query) throws QueryEvaluationException, QueryResultHandlerException Evaluate a tuple query, and create an XML results document. It is still necessary to call end() on the builder after calling this method.- Parameters:
builder
- response builder helper for generating the XML response to the client, which must have had start() called on itquery
- the query to be evaluated- Throws:
