本文整理了Java中org.apache.qpid.proton.message.Message.decode()方法的一些代码示例，展示了Message.decode()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Message.decode()方法的具体详情如下：
包路径：org.apache.qpid.proton.message.Message
类名称：Message
方法名：decode

Message.decode介绍

[英]Decodes the Message from the given ReadableBuffer.

If the buffer given does not contain the fully encoded Message bytes for decode this method will throw an exception to indicate the buffer underflow condition and the message object will be left in an undefined state.
[中]解码来自给定ReadableBuffer的消息。
如果给定的缓冲区不包含用于解码的完全编码的消息字节，此方法将引发异常，以指示缓冲区下溢的情况，消息对象将处于未定义状态。

代码示例

代码示例来源：origin: org.apache.qpid/proton-hawtdispatch

static Message decode(Buffer buffer) {
  Message msg = Message.Factory.create();
  int offset = buffer.offset;
  int len = buffer.length;
  while( len > 0 ) {
    int decoded = msg.decode(buffer.data, offset, len);
    assert decoded > 0: "Make progress decoding the message";
    offset += decoded;
    len -= decoded;
  }
  return msg;
}

/**
 * Given a byte buffer that represents an encoded AMQP Message instance,
 * decode and return the Message.

 * @param encodedBytes

  // For now we must fully decode the message to get at the annotations.
  Message protonMessage = Message.Factory.create();

  return protonMessage;
}
