Hello, Matthew!
Trying to figure out how to tell if set A is a subset of Set B... Is
there anyway in gnuStep? I can't figure out how to querry if a set is
null, or the size of a set...
There is always...
+ (NSCharacterSet *)characterSetWithCharactersInString:(NSString *)aString;
...which you can call with @"" as parameter to get an empty set and
compare (isEqual) to another NSCharacterSet. That's not the same a
comarison to nil, though.
On OS X there is also:
- (BOOL)isSupersetOfSet:(NSCharacterSet *)theOtherSet;
If that is not on GNUstep, maybe someone could add it?
Greetings,
Dirk
