|
<p>A function that splits <code>msg.payload</code> into multiple messages.</p>
|
|
<p>The behaviour is determined by the type of <code>msg.payload</code>:</p>
|
|
<ul>
|
|
<li><b>string</b> - a message is sent for each part of the string after it is split using the specified character, by default a newline (<code>\n</code>).
|
|
<li><b>array</b> - a message is sent for each element of the array</li>
|
|
<li><b>object</b> - a message is sent for each key/value pair of the object. <code>msg.parts.key</code> is set to the key of the property.</li>
|
|
</ul>
|
|
<p>Each message is sent with the <code>msg.parts</code> property set. This is
|
|
an object that provides any subsequent <i>join</i> node the necessary information
|
|
for it to reassemble the messages back into a single one. The object 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>

<script type="text/x-red" data-help-name="join">
|
|
<p>A function that joins the a sequence 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>It can be used without the split node by configuring the required behaviour.</p>
|
|
<p>The type of the resulting message property can be a string, array or object. All of the other message
|
|
properties are taken from the last message received before the message 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 the node is set to construct a string, a <i>join character</i> can be set.</p>
|
|
<p>If the node is set to construct an object, the key used to store each received property can be taken from
|
|
an identified message property.</p>
|
|
<p>The automatic behaviour relies on the received messages to have <b>msg.parts</b> set.
|
|
The object 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>
