Example 5 with ResponsePredicate

use of io.vertx.ext.web.client.predicate.ResponsePredicate in project hono by eclipse.

 * @param sortOptions A list of sort options.
 * @return A future indicating the outcome of the operation. The future will contain the response if the
 *         response contained the expected status code. Otherwise the future will fail.
