ConnectorManager

ConnectorManager coordinates lifecycle and callback wiring for multiple ExchangeConnector instances, managing startup and routing of market data events.

class ConnectorManager {
public:
  void registerConnector(std::shared_ptr<ExchangeConnector> connector);
  void startAll(ExchangeConnector::BookUpdateCallback onBookUpdate,
                ExchangeConnector::TradeCallback onTrade);

private:
  std::map<std::string, std::shared_ptr<ExchangeConnector>> connectors;
};

Purpose

• Aggregate multiple exchange connectors and manage their startup and event forwarding.

Responsibilities

Aspect	Details
Registration	Stores connectors indexed by their exchangeId() value.
Startup	Calls start() on all registered connectors.
Callbacks	Wires trade and book update callbacks to each connector during startup.
Output	Logs startup of each connector to stdout.

Notes

• Assumes connectors are ready to start at the time of startAll() — no deferred registration.
• Wraps callbacks using lambdas to allow mutation and move-only semantics.
• Primarily intended for system bootstrap and orchestration; not used in performance-critical paths.
• Callback dispatch remains connector-local; manager only wires them once.
