XE8-indy10中TIdTCPConnection.Connected函数的源码

indy10中TIdTCPConnection.Connected函数的源码：

function TIdTCPConnection.Connected: Boolean;
var
  // under ARC, convert a weak reference to a strong reference before working with it
  LIOHandler: TIdIOHandler;
begin
  // Its been changed now that IOHandler is not usually nil, but can be before the initial connect
  // and also this keeps it here so the user does not have to access the IOHandler for this and
  // also to allow future control from the connection.
  LIOHandler := IOHandler;
  Result := Assigned(LIOHandler);
  if Result then begin
    Result := LIOHandler.Connected;
  end;
end;
