Examples with QoS org.eclipse.hono.service.metric.MetricsTags.QoS used on opensource projects

Example 1 with QoS

use of org.eclipse.hono.service.metric.MetricsTags.QoS in project hono by eclipse.

the class VertxBasedAmqpProtocolAdapter method onMessageReceived.

/**
 * Processes an AMQP message received from a device.
 * <p>
 * This method settles the transfer with the following outcomes:
 * <ul>
 * <li><em>accepted</em> if the message has been successfully processed.</li>
 * <li><em>rejected</em> if the message could not be processed due to a problem caused by the device.</li>
 * <li><em>released</em> if the message could not be forwarded to a downstream consumer.</li>
 * </ul>
 *
 * @param ctx The context for the message.
 * @return A future indicating the outcome of processing the message.
 *         The future will succeed if the message has been processed successfully, otherwise it
 *         will fail with a {@link ServiceInvocationException}.
