Tools.h++ Class Reference

For both operator++ and operator(), iterating past the last element will return a value equivalent
to boolean false. Continued increments will return a value equivalent to false until reset() is
called.
Persistence
None
Examples
#include<rw/tpmap.h>
#include<iostream.h>
#include<rw/cstring.h>
int main(){
RWTPtrMap<RWCString,int,less<RWCString> > age;
RWTPtrMapIterator<RWCString,int,less<RWCString> > itr(age);
age.insert(new RWCString("John") ,new int(30));
age.insert(new RWCString("Steve"),new int(17));
age.insert(new RWCString("Mark") ,new int(24));
//Insertion is rejected, no duplicates allowed
age.insert(new RWCString("Steve"),new int(24));
for(;itr();)
cout << *itr.key() << "\'s age is " << *itr.value() << endl;
return 0;
}
Program Output
John's age is 30
Mark's age is 24
Steve's age is 17
Public Constructors
RWTPtrMapIterator<K,T,C>(const RWTPtrMap<K,T,C>& rwm);
Creates an iterator for the map rwm. The iterator begins in an undefined state and must be
advanced before the first element will be accessible
Public Member Operators
K*
operator()();
Advances self to the next element, dereferences the resulting iterator and returns its key. If
the iterator has advanced past the last item in the container, the element returned will be a
