### User function | |
The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both). | |
- When used as an Input, the component only impacts the input signature of the user function. | |
- When used as an output, the component only impacts the return signature of the user function. | |
The code snippet below is accurate in cases where the component is used as both an input and an output. | |
