# prism.task.PrismTask

## Constructor

<details>

<summary><code>prism.task.PrismTask</code></summary>

*`class`*` ``prism.task.PrismTask(`*`bool_run: bool = True, func: Optional[Callable[..., Any]] = None`*`)`

* **Parameters**
  * `bool_run`: a boolean indicating whether to run the task. Default is `True`.
  * `func`: optional callable that overwrites the `run` function. Default is `None`.

</details>

{% hint style="warning" %}
**Warning**: you will *never* need to worry about instantiating a `PrismTask` class and setting `bool_run` / `func` when working with your tasks. This is all handled on the backend.
{% endhint %}
