# IsEmpty

> Whether this reference is unset and resolves to no value.

## Definition

* **Type:** Property
* **Namespace:** [Unity.Localization](/engine/6000.7/script-reference/unity/localization.md)
* **Assembly:** UnityEngine.LocalizationRuntimeModule

```csharp
public virtual bool IsEmpty { get; }
```

### Remarks

The base implementation returns `true` when no [TableReference](/engine/6000.7/script-reference/unity/localization/tablereference.md) is assigned. Subclasses extend this to also require a valid entry reference.
