Element Details
-
indexName
A reference to a named index.- Returns:
- the index name
-
keyFields
A list of one or more keys to use in looking up an entry in a given index.- Returns:
- one or more keys
-
-
-
id
An optional identifier for the constraint, which must be unique to only this constraint.- Returns:
- the identifier if provided or an empty string otherwise
