Detailed Description

Abstract base class for all transport-specific client (RPC caller) implementations.

ClientImpl is the intermediate layer between the generic Client<Req,Resp> template and a concrete transport backend (e.g. DdsClientImpl, ShmClientImpl). It inherits from NodeImpl and adds method-client semantics:

• Server-connection detection and notification via detect_connected() / update_connected().
• Blocking wait for server availability with wait_for_connected().
• Synchronous (blocking) RPC call via call().

Connection Detection Flow

// Transport detects server appearance or disappearance:
client_impl->update_connected();
//   -> compares is_connected() against cached state
//   -> notifies the condition variable
//   -> fires the ConnectCallback registered via detect_connected()

Note

Concrete subclasses must implement is_connected() and call().
