# ProcessorInstance.AvailableData

> A temporary collection of data available for enumeration.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine.Audio](/engine/6000.6/script-reference/unityengine/audio.md)
* **Assembly:** UnityEngine.AudioModule

```csharp
public ref struct ProcessorInstance.AvailableData
```

## Remarks

You can enumerate the [ProcessorInstance.AvailableData.Element](/engine/6000.6/script-reference/unityengine/audio/processorinstance/availabledataelement.md)s within using a **foreach** loop over this collection.
