<p>A function that joins a sequence of messages into a single message.</p>
|
||||
<p>Joins sequences of messages into a single message.</p>
|
||||
<p>When paired with the <b>split</b> node, it will automatically join the messages
|
||||
to reverse the split that was performed.</p>
|
||||
<p>The node can join either a specific property of each received message or,
|
||||
if the output type is not string, the entire message.</p>
|
||||
<p>The type of the resulting message property can be:</p>
|
||||
<h3>Inputs</h3>
|
||||
<dl class="message-properties">
|
||||
<dt class="optional">parts<span class="property-type">object</span></dt>
|
||||
<dd>To automatically join a sequence of messages, they should all have
|
||||
this property set. The <b>split</b> node generates this property but it
|
||||
can be manually created. It has the following properties:
|
||||
<ul>
|
||||
<li>a <b>string</b> - created by joining the property of each message with the specified join character.</li>
|
||||
<li><code>id</code> - an identifier for the group of messages</li>
|
||||
<li><code>index</code> - the position within the group</li>
|
||||
<li><code>count</code> - the total number of messages in the group</li>
|
||||
<li><code>type</code> - the type of message - string/array/object</li>
|
||||
<li><code>ch</code> - for a string, the character used to split</li>
|
||||
<li><code>key</code> - for an object, the key of the property this message was created from</li>
|
||||
<li><code>len</code> - for an array, the length of each array section</li>
|
||||
|
||||
</ul>
|

</dd>
|
||||
<dt class="optional">complete</dt>
|
||||
<dd>If set, the node will send its output message in its current state.</dd>
|
||||
</dl>
|
||||
<h3>Details</h3>
|
||||
<p>When configured to join in manual mode, the node is able to join sequences
|
||||
of messages in a variety of ways.</p>
|
||||
<ul>
|
||||
<li>a <b>string</b> - created by joining the selected property of each message with the specified join character.</li>
|
||||
<li>an <b>array</b>.</li>
|
||||
<li>a <b>key/value object</b> - created by using a property of each message to determine the key under which
|
||||
the required value is stored.</li>
|
||||
<li>a <b>merged object</b> - created by merging the property of each message under a single object.</li>
|
||||
</ul>
|
||||
The other properties of the output message are taken from the last message received before the result is sent.</p>
|
||||
<p>A <i>count</i> can be set for how many messages should be received before generating the output message</p>
|
||||
<p>The other properties of the output message are taken from the last message received before the result is sent.</p>
|
||||
<p>A <i>count</i> can be set for how many messages should be received before generating the output message.</p>
|
||||
<p>A <i>timeout</i> can be set to trigger sending the new message using whatever has been received so far.</p>
|
||||
<p>If a message is received with the <b>msg.complete</b> property set, the output message is sent.</p>
|
||||
<p>The automatic behaviour relies on the received messages to have <b>msg.parts</b> set. The split node generates
|
||||
this property, but can be manually created. It has the following properties:</p>
|
||||
<ul>
|
||||
<li><b>id</b> - an identifier for the group of messages</li>
|
||||
<li><b>index</b> - the position within the group</li>
|
||||
<li><b>count</b> - the total number of messages in the group</li>
|
||||
<li><b>type</b> - the type of message - string/array/object</li>
|
||||
<li><b>ch</b> - for a string, the character used to split</li>
|
||||
<li><b>key</b> - for an object, the key of the property this message was created from</li>

||||
