# IPostProcessValueLocale

> Transforms resolved localization values before they are handed back to the caller.

## Definition

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

```csharp
public interface IPostProcessValueLocale
```

## Remarks

Implement this on a [Locale](/engine/6000.7/script-reference/unity/localization/locale.md) subclass to post-process the values resolved for that locale, such as a pseudo-locale that accents, expands, or brackets strings to test how a layout copes. [ResourceDatabase](/engine/6000.7/script-reference/unity/localization/resourcedatabase.md) calls [IPostProcessValueLocale.PostProcessValue](/engine/6000.7/script-reference/unity/localization/ipostprocessvaluelocale/postprocessvalue.md) for resolved string values, after Smart String formatting has run, on both the synchronous and asynchronous paths. The generic signature lets one implementation cover other value types as well. A locale that does not implement this interface leaves resolved values untouched. Mark the implementing locale with SerializableAttribute, because the project's locale list holds locales by managed reference and a type without it deserializes as null.

A pseudo-locale that brackets every resolved string.

## Examples

```csharp
using System;

namespace Unity.Localization.Samples
{
    [Serializable]
    public class PostProcessValueLocaleExample : Locale, IPostProcessValueLocale
    {
        public PostProcessValueLocaleExample() : base("qps-ploc", "Pseudo (bracketed)") { }

        public T PostProcessValue<T>(T value) => value is string text ? (T)(object)$"[{text}]" : value;
    }
}
```
