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.

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

Remarque :

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.
