ServiceAlreadyRegisteredException class final

An exception thrown when an attempt is made to register a service that has already been registered in the service locator.

This exception helps maintain the integrity of the service registry by preventing accidental duplication of service registrations.

Usage: Throws when trying to register a service with the same type more than once.

void registerSingleton<T extends Object>(T instance) {
  if (locator.isRegistered<T>()) {
    throw ServiceAlreadyRegisteredException(T);
  }
  locator._services[T] = instance;
}
