Setclass
Setclass is a term used in computer science to describe a mechanism for attaching classification information to a set of elements. It refers to a way of describing or enforcing properties that apply to all members of a set, or to the set itself, by associating a class label, type, or metadata with the collection. The concept appears in several domain-specific languages and library designs, rather than as a universal language feature.
Implementation approaches vary. One common method is element-level tagging, where each item carries a class tag
Purpose and benefits include enabling efficient querying and dispatch, simplifying validation and policy enforcement, and supporting
Limitations and considerations involve potential overhead from tagging or metadata, risk of inconsistency if member tags
Example: in a hypothetical language, a set of documents could be typed Set<Document, Classified>, allowing queries
