# PoPMeasureBuilder

- Package: [@gooddata/sdk-model](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-model/index.md)
- Kind: class
- Source: https://github.com/gooddata/gooddata-ui-sdk/blob/rel/11.64/libs/sdk-model/src/execution/measure/factory.ts

Builder for period-over-period measures.

Do not instantiate this builder directly, instead use [newPopMeasure()](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-model/sdk-model.newpopmeasure/index.md).

**Signature:**

```typescript
export declare class PoPMeasureBuilder extends MeasureBuilderBase<IPoPMeasureDefinition> 
```
**Extends:** [MeasureBuilderBase](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-model/sdk-model.measurebuilderbase/index.md)&lt;[IPoPMeasureDefinition](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-model/sdk-model.ipopmeasuredefinition/index.md)&gt;

## Remarks

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `PoPMeasureBuilder` class.

For convenience the attribute may be specified by either object reference or as a string - in which case it is assumed this is identifier of the attribute object. |
