satcat5::eth::ChatEcho Class Reference

Detailed Description

Service for echoing ChatProto text messages.

For each received ChatProto message, send a reply containing prefix "You said..." followed by the received message contents. To avoid amplification with multiple ChatEcho services, it always replies to the sender, never to the broadcast address.

Member Function Documentation

frame_rcvd()

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

overrideprotectedvirtual

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.
