Class %iKnow.Objects.MetadataValue

deprecatedpersistent class %iKnow.Objects.MetadataValue extends %Persistent

Note: the use of this class is no longer recommended for accessing elements of a specific domain. For those scenarios, %iKnow.Tables.Utils offers a more flexible and customizable way of projecting iKnow domain data to SQL

This is a read-only object representation wrapping the internal iKnow data structures for Metadata field values.

This class can be used from ObjectScript or SQL to access a single or small number of entries, but the storage mappings are not meant to support elaborate or complex queries targeting this SQL table.

Please use the predefined queries in %iKnow.Queries.MetadataAPI and other query classes to consult metadata as the internal global structures are designed to optimize performance for these queries rather than general-purpose access.

• property Field as %iKnow.Objects.MetadataField [ Calculated ];

• property FieldId as %Integer;

• property SourceId as %Integer;

• property Value as %String(MAXLEN=2000) [ Calculated ];

Indices

•index (PKINDEX on DomainId,SourceId,FieldId) [IdKey,PrimaryKey,Unique];
