RWTValHashTable<T>
Synopsis #include <rw/tvhset.h>
unsigned hashFun(const T&);
RWTValHashSet(hashFun) set;
Description RWTValHashSet<T> is a derived class of RWTValHashTable<T> where the
insert() function has been overridden to accept only one item of a given
value. Hence, each item in the collection will be unique.
As with class RWTValHashTable<T> , you must supply a hashing function to
the constructor.
The class T must have:
• well-defined copy semantics ( T::T(const T&) or equiv.);
• well-defined assignment semantics ( T::operator=(const T&) or equiv.);
• well-defined equality semantics ( T::operator==(const T&) ).
