<p>Route messages based on their property values.</p>
|
|
<h3>Details</h3>
|
|
<p>When a message arrives, the node will evaluate each of the defined rules
|
|
and forward the message to the corresponding outputs of any matching rules.</p>
|
|
<p>Optionally, the node can be set to stop evaluating rules once it finds one
|
|
that matches.</p>
|
|
<p>The rules can be evaluated against an individual message property, a flow or global
|
|
context property or the result of a JSONata expression.</p>
|
|
<h3>Rules</h3>
|
|
<p>Routing rules are categorized into three:</p>

<h3>Repair Sequence</h3>
|
|
<p>If <b>repair sequence (reconstruct parts property of outgoing messages)</b> checkbox is selected, <code>msg.parts</code> property are reconstructed for each port to make forks of valid sequences. Otherwise, <code>msg.parts</code> property of incoming messages are passed through.</p>
|

<h3>Note:</h3>
|
|
<p>This node internally keeps messages for its operation if <b>repair sequence</b> checkbox is ON. In order to prevent unexpected memory usage, maximum number of messages kept can be specified by <code>switchMaxKeptMsgsCount</code> property in <b>settings.js</b>.</p>
