MultiGate

The MultiGate node is a powerful flow control node that allows you to direct the flow of execution in your spell to multiple outputs based on certain conditions. It’s particularly useful when you need to perform different actions or computations in parallel or conditionally.

​
Inputs

  1. flow (flow): The main input flow that triggers the MultiGate node.
  2. reset (flow): An optional reset flow that, when triggered, resets the MultiGate to its initial state.
  3. loop (boolean, default: false): When set to true, the MultiGate will continuously loop through its outputs.
  4. startIndex (integer, default: 0): Specifies the initial output index when the node is first triggered.

​
Outputs

  1. 1 (flow): The first output flow.
  2. 2 (flow): The second output flow.
  3. 3 (flow): The third output flow.

​
Configuration

The MultiGate node does not have any additional configuration options.

​
Usage

  1. Connect the main flow that you want to control to the flow input of the MultiGate node.
  2. Optionally, connect a reset flow to the reset input if you want to be able to reset the MultiGate to its initial state.
  3. Set the loop input to true if you want the MultiGate to continuously loop through its outputs.
  4. Specify the startIndex input to control which output the MultiGate should activate first (0-indexed).
  5. Connect the desired actions or nodes to the corresponding outputs of the MultiGate.
When the flow input is triggered, the MultiGate will activate one of its outputs based on the current internal state. If loop is true, it will keep cycling through the outputs on each subsequent trigger. The reset input allows you to reset the internal state back to the startIndex.

Example

Here’s an example of how you might use the MultiGate node in a spell: 
1. HTTP Request
   URL: https://api.example.com/data
   
   |
   | flow
   v
   
2. MultiGate
   loop: true
   
   1 |              2 |             3 |
     v                v               v 
     
3. Process Data   4. Log Result   5. Update Dashboard
In this example, the MultiGate node is used to control the flow after an HTTP request. The first output is connected to a node that processes the returned data. The second output logs the result somewhere. The third output sends the data to update a dashboard. With loop set to true, the MultiGate will alternate between these three actions on each subsequent request.

Best Practices

  • Use the MultiGate judiciously to keep your spell organized and maintainable. Too many branching paths can become confusing.
  • Provide clear labels or comments for each output to indicate its purpose.
  • Consider using variables or the reset input to control the MultiGate’s behavior dynamically during the spell’s execution.

​
Common Pitfalls

  • Remember that the MultiGate’s outputs are 0-indexed when setting the startIndex. An index out of bounds will cause an error.
  • If loop is false and the MultiGate reaches the end of its outputs, subsequent triggers to the flow input will have no effect until it is reset.
  • Be cautious when using the MultiGate inside a loop to avoid infinite execution cycles.
