# clsManualClassDescriptionAbbreviationCollection
Enumerates abbreviated manual class description rows. Its factory methods retrieve these rows through BOF criteria objects, and its helpers expose the keyed or effective-dated filters callers use after load.
## Purpose
- Enumerates abbreviated manual class description rows.
- Its factory methods retrieve these rows through BOF criteria objects, and its helpers expose the keyed or effective-dated filters callers use after load.
## Context
- Namespace: `SAIF.Business.Policy.Rating`
- Assembly/package: `SAIF.Business.Policy.Rating`

## Behavioral notes
- Rows are loaded through the BOF data portal first; the collection then applies any additional in-memory filtering or keyed selection.
## Constraints and usage notes
- Lookups that do not find a matching row return `Nothing` or an empty filtered collection, so callers should handle missing results explicitly.
