# ComponentResourceReleaseHandler<T>

> The signature of a [ReleaseComponentResources ] method: it receives the released component's own data by reference and frees what that component allocated.

## Definition

* **Type:** Delegate
* **Namespace:** [UnityEngine.UIElements](/engine/6000.7/script-reference/unityengine/uielements.md)
* **Assembly:** UnityEngine.UIElementsModule

```csharp
public delegate void ComponentResourceReleaseHandler<T>(ref T component) where T : struct, IVisualElementComponent
```

## Remarks

You don't write this delegate yourself. Unity's source generator wraps the component's `[ReleaseComponentResources]` method in one and hands it to the runtime, which invokes it on the main thread once per released component instance.
