Example 31 with EventBusMessage

use of org.eclipse.hono.util.EventBusMessage in project hono by eclipse.

the class AbstractEventBusHttpEndpoint method getDefaultResponseHandler.

/**
 * Gets a response handler that implements the default behavior for responding to an HTTP request.

 * <li>If the status code represents an error condition (i.e. the code is &gt;= 400),
 * then the JSON object passed in to the returned handler is written to the response body.</li>
 * <li>Otherwise, if the given filter evaluates to {@code true} for the status code,
 * the given custom handler is invoked (if not {@code null}), then
 * the JSON object is written to the response body and </li>
 * </ol>

 * @param ctx The routing context of the request.
 * @param successfulOutcomeFilter A predicate that evaluates to {@code true} for the status code(s) representing a
 *                           successful outcome.
 * @param customHandler An (optional) handler for post processing the HTTP response, e.g. to set any additional HTTP
 *                        headers. The handler <em>must not</em> write to response body. May be {@code null}.
