Detailed Description

template<typename CommandHandler, typename CommandParser>
struct radix_relay::core::event_handler< CommandHandler, CommandParser >

Dispatches parsed command events to the command handler.

Template Parameters

CommandHandler	Callable type that handles typed command events via operator()
CommandParser	Parser type with command_variant_t type trait and parse() method

Uses Chain of Responsibility (parser) + Visitor (command_handler) pattern:

• Parser converts raw string to strongly-typed command variant
• std::visit dispatches the variant to command_handler

Constructor & Destructor Documentation

event_handler()

template<typename CommandHandler , typename CommandParser >

radix_relay::core::event_handler< CommandHandler, CommandParser >::event_handler ( std::shared_ptr< CommandHandler >  command_handler, std::shared_ptr< CommandParser >  parser, const out_queues_t &    )

inlineexplicit

Constructs an event handler with command handler and parser.

Parameters

command_handler	Command handler that handles typed commands (shared ownership)
parser	Command parser for converting strings to typed events
queues	Output queues (stored for type compatibility, handler uses its own references)
