详细描述

Abstract transport node base classes used by all VLink node implementations.

This header defines two base classes that form the backbone of the VLink transport abstraction:

• AbstractNode – minimal interface for retrieving the underlying native transport handle (e.g. a DDS DataWriter pointer).
• NodeImpl – the main base class for PublisherImpl, SubscriberImpl, ServerImpl, ClientImpl, SetterImpl, and GetterImpl. It provides common infrastructure:

Feature	API
Transport initialise	init() / deinit()
Zero-copy loan	loan() / return_loan()
Suspend / resume	suspend() / resume()
Interrupt	interrupt() / reset_interrupted()
Property store	set_property() / get_property()
Message loop attach	attach() / detach() / get_message_loop()
Status callback	register_status_handler() / call_status()
Data recording	set_record_path() / try_record()
Discovery registration	init_ext() / deinit_ext()
Version check	check_version()
Global init	global_init() – called once per process

Callback Types

NodeImpl defines the standardised callback signatures used throughout all transport backends:

Type	Signature	Used by
ConnectCallback	void(bool)	PublisherImpl, ClientImpl, ServerImpl
StatusCallback	void(const Status::BasePtr&)	DDS status events
SyncCallback	void()	SetterImpl sync
ReqRespCallback	void(uint64_t, const Bytes&, Bytes*)	ServerImpl listen
MsgCallback	void(const Bytes&)	SubscriberImpl, GetterImpl
IntraMsgCallback	void(const IntraData&)	intra:// subscriber
