Member Function Documentation

frame_rcvd()

virtual void satcat5::net::Protocol::frame_rcvd ( satcat5::io::LimitedRead &  src )

pure virtualinherited

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.
