satcat5::coap::EndpointSppFwd Class Reference

Detailed Description

EndpointSpp variant that forwards all requests to another Endpoint.

Variant CCSDS-SPP server used in conjunction with another CoAP server on a different network interface. This allows one backing Endpoint to serve the same CoAP resources to multiple networks.

coap_error()

void EndpointSppFwd::coap_error ( Connection *  obj )

overrideprotectedvirtual

The Child class overrides these event-handlers:

• coap_request = Received incoming request. The default implementation always responds with "5.01 Not Implemented". The child class SHOULD override this method if it accepts incoming requests. Call open_response() or open_separate() to send the reply.

  See also

  coap::Connection.

• coap_response = Received the response to a pending request. The default implementation discards the incoming response. The child class SHOULD override this method if it issues requests.

  See also

  Connection::open_request. Multicast queries may result in multiple responses.

• coap_reqwait = Received duplicate request in "await" state. Child classes that require special event handling, such as reverse-proxies, MAY override this method as needed.
• coap_separate = Received separated-response notification. Child classes that require special event handling, such as reverse-proxies, MAY override this method as needed.
• coap_error = A pending request failed (i.e., reset or timeout). The child class SHOULD override this method if it issues requests, in order to process errors.
• coap_ping = Received response to a ping request. The child class MAY override this method if it issues ping requests.

  See also

  Connection::ping.

• coap_timeout = Benign timeout for a non-confirmable request. For unicast queries, this event indicates no response. For multicast queries, this event marks the end of the waiting period, whether or not request(s) were received.

frame_rcvd()

void Endpoint::frame_rcvd ( satcat5::io::LimitedRead &  src )

overrideprotectedvirtualinherited

Dispatch calls frame_rcvd(...) for each incoming frame with with a matching net::Type value.

The child class SHOULD read the frame contents from the provided "src" object, which is only valid until the function returns.

To send a reply:

• Call m_iface->open_reply() to obtain a Writable object. (This also writes out any applicable frame headers.)
• Write frame contents, then call write_finalize().

The child class MUST override this method.

Implements satcat5::net::Protocol.

Set the preferred connection for outgoing requests.

Usually called indirectly through ManageSpp or ManageUdp.
