Abstract: CardTable manages hash tables that map from LONG CARDNIALs to REFs. RefID uses CardTable to maintain associations between IDs and REFs. An ID is simply a laundered REF, which can be passed across an RPC connection.

CardTable
CardTable manages hash tables that map from LONG CARDNIALs to REFs. It is similar to RefTab (in fact, the implementation is identical). Access to CardTables is monitorized for concurrent access.
See the interface for further documentation.
RefID
RefID creates IDs for REFs and maps between the two. An ID is simply a laundered REF, which can be passed across an RPC connection. When a REF is "sealed" into an ID, this package holds onto the REF so that it is not garbage collected. IDs must be explicitly released to indicate that interest in the REF no longer exists.
