Classify characters [virtual]
Virtual protected member function called by ctype::is to classify characters.
Polymorphic derived classes can overwrite the behavior of this function.
See ctype::is for its default behavior in ctype.
char specialization of ctype (
ctype<char>) does not have this member, as its member ctype<char>::is returns its results directly.
