|

<p>根据各种规则创建消息序列。</p>
|
||
<h3>详细</h3>
|
||
<p>有三种创建消息序列的模式：</p>
|
||
<dl>
|
||
<dt>讯息数</dt>
|
||
<dd>将消息分组为给定长度的序列。 <b>overlap</b>（重叠）选项指定在一个序列的末尾应重复多少消息。</dd>
|
||
|
||
<dt>时间间隔</dt>
|
||
<dd>对在指定时间间隔内到达的邮件进行分组。如果在该时间间隔内没有消息到达，则该节点可以选择发送空消息。</dd>
|
||
|
||
<dt>串联序列</dt>
|
||
<dd>通过串联输入序列来创建消息序列。每条消息必须具有<code>msg.topic</code>属性和标识其序列的<code>msg.parts</code>属性。该节点配置有<code>topic</code>值列表，以标识所连接的顺序序列。
|
||
</dd>
|
||
</dl>
|
||
<h4>储存讯息</h4>
|
||
<p>该节点将在内部缓冲消息，以便跨序列工作。运行时设置<code>nodeMessageBufferMaxLength</code>可用于限制节点将缓存多少消息。</p>
|
||
<p>如果接收到的消息设置了<code>msg.reset</code>属性，则缓冲的消息将被删除并且不会发送。</p>
