    • refer

      public <T> Invoker<T> refer(Class<T> type, URL url) throws RpcException
      Description copied from interface: Protocol
      Refer a remote service:
      1. When user calls `invoke()` method of `Invoker` object which's returned from `refer()` call, the protocol needs to correspondingly execute `invoke()` method of `Invoker` object
      2. It's protocol's responsibility to implement `Invoker` which's returned from `refer()`. Generally speaking, protocol sends remote request in the `Invoker` implementation.
      3. When there's check=false set in URL, the implementation must not throw exception but try to recover when connection fails.
      Specified by:
      refer in interface Protocol
      Type Parameters:
      T - Service type
      Parameters:
      type - Service class
      url - URL address for the remote service
      Returns:
      invoker service's local proxy
