<p>根據各種規則創建消息序列。</p>
|
||
<h3>詳細</h3>
|
||
<p>有三種創建消息序列的模式：</p>
|
||
<dl>
|
||
<dt>訊息數</dt>
|
||
<dd>將消息分組爲給定長度的序列。 <b>overlap</b>（重疊）選項指定在一個序列的末尾應重複多少消息。</dd>
|
||
|
||
<dt>時間間隔</dt>
|
||
<dd>對在指定時間間隔內到達的郵件進行分組。如果在該時間間隔內沒有消息到達，則該節點可以選擇發送空消息。</dd>
|
||
|
||
<dt>串聯序列</dt>
|
||
<dd>通過串聯輸入序列來創建消息序列。每條消息必須具有<code>msg.topic</code>屬性和標識其序列的<code>msg.parts</code>屬性。該節點配置有<code>topic</code>值列表，以標識所連接的順序序列。
|
||
</dd>
|
||
</dl>
|
||
<h4>儲存訊息</h4>
|
||
<p>該節點將在內部緩衝消息，以便跨序列工作。運行時設置<code>nodeMessageBufferMaxLength</code>可用于限制節點將緩存多少消息。</p>
