Class %iKnow.Objects.MetadataField

persistent class %iKnow.Objects.MetadataField extends %Persistent

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

This class can be used from Cache 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.
