persistent class %iKnow.Objects.MetadataValue
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.
parameter READONLY = 1;
READONLY = 1 means that objects can be created, opened but not saved or deleted.
Tables are projected to SQL as READONLY.
