Synopsis

#include <rw/tpdlist.h>
template <class T, class A=std::allocator<T*> >
class  RWTPtrDlistConstIterator

Description

RWTPtrDlistConstIterator provides a const iterator interface to the Standard C++ Library-based collections. This iterator prohibits any changes to the underlying collection.

The order of iteration over an RWTPtrDlist is dependent on the order of the values 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 preincrement or operator().

For both operator++ and operator(), iterating past the last element returns a value equivalent to boolean false. Continued increments return a value equivalent to false until reset() is called. For operator--, decrementing past the first element returns a value equivalent to false.

Persistence

None
