Example 11 with CommandResponse

use of org.eclipse.hono.client.command.CommandResponse in project hono by eclipse.

the class CommandResponseResource method uploadCommandResponseMessage.

/**
 * Forwards a command response to a downstream application.
 *
 * @param context The context representing the command response to be forwarded.
 * @return A future indicating the outcome of the operation.
 *         The future will be succeeded if the message has been forwarded successfully.
 *         In this case one of the context's <em>respond</em> methods will have been invoked to send a CoAP response
 *         back to the device.
 *         Otherwise the future will be failed with a {@link org.eclipse.hono.client.ServiceInvocationException}.
 * @throws NullPointerException if context is {@code null}.
