<header><h1>Logic components in Langflow</h1></header>
|
||
<p>Logic components provide functionalities for routing, conditional processing, and flow management.</p>
|
||
<h2 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="use-a-logic-component-in-a-flow">Use a logic component in a flow<a href="#use-a-logic-component-in-a-flow" class="hash-link" aria-label="Direct link to Use a logic component in a flow" title="Direct link to Use a logic component in a flow"></a></h2>
|
||
<p>This flow creates a summarizing "for each" loop with the <a href="/components-logic#loop">Loop</a> component.</p>
|
||
<p>The component iterates over a list of <a href="/concepts-objects#data-object">Data</a> objects until it's completed, and then the <strong>Done</strong> loop aggregates the results.</p>
|
||
<p>The <strong>File</strong> component loads text files from your local machine, and then the <strong>Parse Data</strong> component parses them into a list of structured <code>Data</code> objects.
|
||
The <strong>Loop</strong> component passes each <code>Data</code> object to a <strong>Prompt</strong> to be summarized.</p>
|
||
<p>When the <strong>Loop</strong> component runs out of <code>Data</code>, the <strong>Done</strong> loop activates, which counts the number of pages and summarizes their tone with another <strong>Prompt</strong>.
|
||
This is represented in Langflow by connecting the Parse Data component's <strong>Data List</strong> output to the Loop component's <code>Data</code> loop input.</p>

<p>This component allows you to run any flow stored in your Langflow database without opening the flow editor.</p>

<p>The Run Flow component can also be used as a tool when connected to an <a href="/components-agents">Agent</a>. The <code>name</code> and <code>description</code> metadata that the Agent uses to register the tool are created automatically.</p>
|
||
<p>When you select a flow, the component fetches the flow's graph structure and uses it to generate the inputs and outputs for the Run Flow component.</p>
|
||
<p>To use the Run Flow component as a tool, do the following:</p>
|
||
<ol>
|
||
<li>Add the <strong>Run Flow</strong> component to the <a href="/starter-projects-simple-agent">Simple Agent</a> flow.</li>
|
||
<li>In the <strong>Flow Name</strong> menu, select the sub-flow you want to run.
|
||
The appearance of the <strong>Run Flow</strong> component changes to reflect the inputs and outputs of the selected flow.</li>
|
||
<li>On the <strong>Run Flow</strong> component, enable <strong>Tool Mode</strong>.</li>
|
||
<li>Connect the <strong>Run Flow</strong> component to the <strong>Toolset</strong> input of the Agent.
|
||
Your flow should now look like this:
