HeaderExchangeChannel 类的 send 方法是否能直接调用 channel.se

我使用的是 dubbo2.7.2

我看了下 github 上的最新源码，如下：

public void send(Object message, boolean sent) throws RemotingException { if (closed) { throw new RemotingException(this.getLocalAddress(), null, "Failed to send message " + message + ", cause: The channel " + this + " is closed!"); } if (message instanceof Request || message instanceof Response || message instanceof String) { channel.send(message, sent); } else { Request request = new Request(); request.setVersion(Version.getProtocolVersion()); request.setTwoWay(false); request.setData(message); channel.send(request, sent); } }

为啥不能直接调用 channel.send(message, sent) ？这是基于什么考虑了？
