Enumeration of enumerations

[Trazom]

Hi, does anyone know how to do an enumeration of differentes enumerations.
Example: enum Units{WeightUnits, TimeUnits, ...}

Thanks.

Greets,

Do you mean contains them all at once? Perhaps you may want to consider
a "union" of enumerated types instead. You can have a "union Unit {}" that
can contain each type of unit. If you want to know which type of
enumeration is contained, consider a "struct" that containes and enumerated
type which defines the type of enumeration contained in the "struct" and the
union of all possible enumerations. (Try saying that 10 times fast.) :)

Regards,

Joe

change this to something like...

enum Units{WeightUnits, TimeUnits, ..., NumberOfUnits,
FirstUnits=WeightUnits, LastUnits = NumberOfUnits-1);

now write

for (int i = FirstUnits; i <= LastUnits; i++) {
Units u = Units(i);
...
}

alternatively, supply an appropriate operator++ for Units and you can write

for (Units u = FirstUnits; u <= LastUnits; u++) {
...
}
