<p>Route messages based on their property values or sequence position.</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>
|
|
<h4>Rules</h4>
|
|
<p>There are four types of rule:</p>
|
|
<ol>
|
|
<li><b>Value</b> rules are evaluated against the configured property</li>
|
|
<li><b>Sequence</b> rules can be used on message sequences, such as those
|
|
generated by the Split node</li>
|
|
<li>A JSONata <b>Expression</b> can be provided that will be evaluated
|
|
against the whole message and will match if the expression returns
|
|
a true value.</li>
|
|
<li>An <b>Otherwise</b> rule can be used to match if none of the preceeding
|
|
rules have matched.</li>
|
|
</ol>
|
|
<h4>Notes</h4>
|
|
<p>The <code>is true/false</code> and <code>is null</code> rules perform strict
|
|
comparisons against those types. They do not convert between types.</p>
|
|
<p>The <code>is empty</code> rule passes for Strings, Arrays and Buffers that have
|
|
a length of 0, or Objects that have no properties. It does not pass for <code>null</code>
|
|
or <code>undefined</code> values.</p>
|
|
<h4>Handling message sequences</h4>
|
|
<p>By default, the node does not modify the <code>msg.parts</code> property of messages
|
|
that are part of a sequence.</p>
|
|
<p>The <b>recreate message sequences</b> option can be enabled to generate new message sequences
|
|
for each rule that matches. In this mode, the node will buffer the entire incoming
|
|
sequence before sending the new sequences on. The runtime setting <code>nodeMessageBufferMaxLength</code>
|
|
can be used to limit how many messages nodes will buffer.</p>
