Actually with my system (LexiMUD) I wouldn't have a problem - I use a
map<VNum, *> class (actually a custom written one) that stores everything
in an AVL tree (sorta like a Red/Black). Thus:
class VId {
public:
string zone;
UInt16 number; // Note: I use sign- and size-qualified
types
bool operator <(const VId v);
...
};
bool VId::operator<(const VId v) {
// If VId::zone is a char *, use str_cmp
if (zone < v.zone || (zone == v.zone && number < v.number)) return
true;
// zone == v.zone
return false; // zone == v.zone && number >= v.number, or zone >
v.zone
}
Finally, if you want some speedup, instead of string zone, use an index
into the zone list.
