# DataPointFacadeBase Class

> DataPointFacadeBase abstract base class for V1 data point facades, exposing the common field metadata and validator properties wrapped from a ResultsDataPoint.

## Definition

* Namespace: `UiPath.DocumentProcessing.Contracts.Extensions.Navigator.V1`
* Assembly: `UiPath.DocumentProcessing.Contracts`

## Description

`DataPointFacadeBase` is the abstract base class for the data point facades [BasicDataPoint](basicdatapoint-class.md), [TableDataPoint](tabledatapoint-class.md), [FieldGroupDataPoint](fieldgroupdatapoint-class.md), and [WildcardDataPoint](wildcarddatapoint-class.md).

It wraps a single [ResultsDataPoint](results-data-point-class.md) and exposes its field metadata and validator information as strongly-typed properties. It is not instantiated directly.
