) const;

Remarks

Classes and attributes are identified by their local classid and full attributeid.

A full attributeid is a UINT64 with the high 32 bits set to the local classid and the low 32 bits set to the attributeid (the index of the attribute in the class).

A full attributeid can be built using the FULLATTRIBUTEID macro.
