Detailed Description

Transport-neutral base class for every method-model server implementation.

This is an internal implementation header used by the public Server template; applications should depend on server.h. ServerImpl extends NodeImpl with the responder-side bookkeeping: it tracks whether a listen() callback has been installed, whether a response is expected and whether the reply is delivered synchronously inside the request callback or asynchronously via reply().

ImplType

The constructor stamps impl_type with kServer, advertising the role to discovery and recording layers.

Lifecycle

• Construction stamps the impl type.
• The public Server template calls listen() once the user installs a request handler; is_listened becomes true on success.
• init() / deinit() inherited from NodeImpl bring the transport up.
• Synchronous mode writes the response into the buffer supplied to the handler; asynchronous mode requires a later reply() call.

Role table

Capability	Provider
Request callback registration	Subclass override of listen()
Client presence query	Subclass override of has_clients() (optional)
Deferred response delivery	Subclass override of reply() for async transports
Sync / async behaviour flags	is_resp_type / is_sync_type (set by public layer)

Internal API contract

Method	Default	Subclass duty
listen(ReqRespCallback&&)	Pure virtual	Bind transport receiver
has_clients() const	Returns false	Report client presence
reply(req_id, bytes, is_sync)	Warns on async path	Implement deferred reply
