<p>Create virtual wires between flows.</p>
<h3>Details</h3>
<p>The node can be connected to any <code>link out</code> node that exists on any tab.
Once connected, they behave as if they were wired together.</p>
<p>The wires between link nodes are only displayed when a link node is selected.
If there are any wires to other tabs, a virtual node is shown that can be clicked
on to jump to the appropriate tab.</p>
<p><b>Note: </b>Links cannot be created going into, or out of, a subflow.</p>

<p>This node can be configured to either send messages to all <code>link in</code>
nodes it is connected to, or to send a response back to the <code>link call</code>
node that triggered the flow.</p>
2021-09-29 15:46:09 +02:00
<p>When in 'send to all' mode, the wires between link nodes are only displayed when
the node is selected. If there are any wires to other tabs, a virtual node
is shown that can be clicked on to jump to the appropriate tab.</p>

<p>Calls a flow that starts with a <code>link in</code> node and passes on the response.</p>
<h3>Inputs</h3>
<dl class="message-properties">
2022-02-28 20:01:15 +01:00
<dt class="optional">target<span class="property-type">string</span></dt>
<dd>When the option <b>Link Type</b> is set to "Dynamic target", set <code>msg.target</code> to the name of the
<code>link in</code> node you wish to call.</dd>
</dl>
<h3>Details</h3>
<p>This node can be connected to a <code>link in</code> node that exists on any tab.
The flow connected to that node must end with a <code>link out</code> node configured
in 'return' mode.</p>
<p>When this node receives a message, it is passed to the connected <code>link in</code> node.
It then waits for a response which it then sends on.</p>
<p>If no response is received within the configured timeout, default 30 seconds, the node
will log an error that can be caught using the <code>catch</code> node.</p>
<p>When the option <b>Link Type</b> is set to "Dynamic target" <code>msg.target</code> can be used to call a
<code>link in</code> by name or id.
<ul>
<li>If there is a <code>link in</code> nodes with the same id, it will be called</li>
<li>If there are two or more <code>link in</code> nodes with the same name, an error will be raised</li>
2022-02-28 20:01:15 +01:00
<li>A <code>link call</code> cannot call a <code>link in</code> node inside a subflow</li>
</ul>
</p>
The flow connected to that node must end with a <code>link out</code> node configured
in 'return' mode.</p>
