# IJobForExtensions

> Contains extension methods for jobs implementing the IJobFor interface.

## Definition

* **Type:** Class
* **Namespace:** [Unity.Jobs](/engine/6000.7/script-reference/unity/jobs.md)
* **Assembly:** UnityEngine.ManagedKernelModule

```csharp
public static class IJobForExtensions
```

## Remarks

The methods in this extension class add an instance of a job to the work queue, while [IJobFor.Execute](/engine/6000.7/script-reference/unity/jobs/ijobfor/execute.md) defines how to perform an asynchronous task. Use [IJobForExtensions.ScheduleByRef](/engine/6000.7/script-reference/unity/jobs/ijobforextensions/schedulebyref.md) to request asynchronous execution, or [IJobForExtensions.RunByRef](/engine/6000.7/script-reference/unity/jobs/ijobforextensions/runbyref.md) to execute the job immediately on the main thread.
