FieldLookupBase Class

FieldLookupBase abstract base class of the V1 navigator facades, defining how a lookup string resolves to a field by field ID or display name.

Definition

  • Namespace: UiPath.DocumentProcessing.Contracts.Extensions.Navigator.V1
  • Assembly: UiPath.DocumentProcessing.Contracts

Description

FieldLookupBase is the abstract base class for the V1 navigator facades. It holds a collection of ResultsDataPoint objects and resolves a lookup string to a single field.

It is not instantiated directly. Its field-resolution behavior is inherited by ComponentCollectionFacade and ResultsValueFacadeBase, and therefore by every facade derived from them.

Field lookup resolution

A lookup string passed to navigation members (for example, fieldLookup, tableLookup, or columnLookup) resolves in the following order:

  • Match by field ID, either fully qualified or by the segment after the last ., compared case-insensitively.
  • If no field matches by ID, match by field display name, compared case-insensitively.

The lookup throws System.ArgumentException when:

  • More than one field matches the ID.
  • More than one field matches the display name.
  • No field matches either the ID or the display name.

ConstructorDescription
FieldLookupBase(ResultsDataPoint[] dataPoints)Initializes a new instance over the supplied data points. A null array is treated as an empty collection.
Note:

This class exposes its data point collection and lookup method as protected members to derived facades. It has no public members other than the constructor.
