The ITfCategoryMgr interface manages categories of objects for text services. The TSF manager implements this interface.
TSF categories help organize objects identified by a globally unique identifier ( GUID ). For example, a class identifier ( CLSID ) identifies a text service, and a GUID identifies the TSF compartment, TSF properties, and TSF display attributes. To group and organize multiple GUIDs, TSF uses category identifiers ( CATIDs).
The category manager uses an internal table, accessed with keys called GUID atoms to cache the GUIDs. Access to GUIDs is efficient using these atoms. When a GUID is obtained using its atom, the GUID description and value can be obtained from the Windows registry.
