      There are five separate iterator helper classes, each for a -different category of iterator. Here is a summary of the core set of -operators that the custom iterator must define, and the extra operators -that are created by the helper classes. These classes cannot be used for base class chaining. For convenience, the helper -classes also fill in all of the typedef's required of iterators by the -C++ standard (iterator_category, value_type, -etc.).

      There are five iterator operator class templates, each for a different +category of iterator. The following table shows the operator groups +for any category that a custom iterator could define. These class +templates have an additional optional template parameter B, +which is not shown, to support base class chaining.
