template<class T, class C = std::less<T>, class A = std::allocator<T*>>
class RWTPtrSetIterator< T, C, A >
- Deprecated
- As of SourcePro 12.5, use RWTPtrSet::iterator to iterate over the elements in this collection.
RWTPtrSetIterator provides an iterator interface to the C++ Standard Library-based collection represented by RWTPtrSet. (An STL iterator interface is provided through RWTPtrSet::iterator.)
The order of iteration over an RWTPtrSet is dependent on the comparator object supplied as applied to the values stored in the container.
The current item referenced by this iterator is undefined after construction or after a call to reset(). The iterator becomes valid after being advanced with either a pre-increment or operator()().
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.
The value
type must have operator==
and operator<
defined. This requirement is imposed by the C++ Standard Library.

return 0;

Program Output
template<class T , class C = std::less<T>, class A = std::allocator<T*>>
Advances self to the next element, dereferences the resulting iterator, and returns its value. If the iterator has advanced past the last item in the container, rwnil will be returned.
template<class T , class C = std::less<T>, class A = std::allocator<T*>>
Advances self to the next element. If the iterator has been reset or just created, self will now reference the first element. If, before iteration, self referenced the last association in the set, self will now reference an undefined value, and a value equivalent to false
will be returned. Otherwise, a value equivalent to true
is returned.
