> **Alpha API.** Initial API, highly likely to change outside SemVer. Don't build on it in production. See [API maturity](https://www.gooddata.ai/docs/gooddata-ui/latest/integrations/platform/api-maturity/index.md).
> 

Type-guard testing whether the provided object is an All time dashboard date filter with `emptyValueHandling` explicitly defined.

**Signature:**

```typescript
export declare function isAllTimeDashboardDateFilterWithEmptyValueHandling(obj: unknown): obj is IDashboardDateFilter & {
    dateFilter: {
        emptyValueHandling: EmptyValues;
    };
};
```

## Parameters

| Parameter | Type | Description |
| --- | --- | --- |
| obj | unknown |  |

**Returns:**

obj is [IDashboardDateFilter](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-model/sdk-model.idashboarddatefilter/index.md) & { dateFilter: { emptyValueHandling: [EmptyValues](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-model/sdk-model.emptyvalues/index.md); }; }

## Remarks

This is useful to distinguish between: - a "noop" All time filter (implicit default, no additional config), and - an All time filter that carries extra configuration (e.g. empty date values handling).
