Introduce a CoapMessage class/interface ?

[sbernard31]

I don't know if this is a good idea but I face some situation where I need to handle a coap request OR a coap (separated) response in a same way. This is not too surprising as from a CoAP RFC point of view all request and response are conceptually a CoAP Message.

In my case, I need the remote peer address and the transport context of the message.

Easy one would be to add helper method, would that be enough?

I'm not sure to see how it will looks like ?

Something like:

static InetSocketAddress getPeerAddress(Object coap) {
...

static TransportContext getTransportContext(Object coap) {
...

OK I get it but my question was more about having a kind of Parent class (e.g. CoapMessage) for CoapRequest, CoapResponse, SeparatedResponse. At first sight (maybe I'm wrong) I think this could make java-coap user code more elegant.

Regarding adding this static method, to be honest, I'm not sure will really makes my user code better. 🤔

Anyway, maybe better to work first on #84 and see if you also need this kind of abstraction in java-coap code too ?
