QcIndexId Class

template <typename Tag> class QcIndexId

The index of a definition in a list of its own kind, as a type of its own per list (decision E-952): Tag tells the lists apart, so an index of one list cannot pass for one of another. More...

int	index() const

Detailed Description

It converts neither from nor to an integer by itself: codecs write index() as the integer of the format and construct the id from the integer they read. A default-constructed id is the first entry (index 0). Ids order and hash by their index; QcIdList indexes a list by them.
