persistent class %iKnow.Objects.EntityUnique 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 unique Entities.

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.EntityAPI and other query classes to consult Entity data as the internal global structures are designed to optimize performance for these queries rather than general-purpose access.

Note: the EntUni index only works for entities up to 150 characters.

NOTE: This object assumes all underlying data structures are present. Use domain-specific copies of these objects for domains where not all indices are built. See also the GenerateAllObjectsForDomain() method in %iKnow.Objects.Utils.

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