<script type="text/html" data-help-name="link in">

|
<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>

<script type="text/html" data-help-name="link out">
|
|
<p>Create virtual wires between flows.</p>
|
|
<h3>Details</h3>
|
|
<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>
|
|
<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><b>Note: </b>Links cannot be created going into, or out of, a subflow.</p>

|
<script type="text/html" data-help-name="link call">
|
|
<p>Calls a flow that starts with a <code>link in</code> node and passes on the response.</p>
|
|
<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.</o>
|
|
<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>
