class BidirectionalIterator
: public ForwardIterator<T, ITER_IMP, TAG_TYPE>Given an ITER_IMP type that implements a minimal subset of an iterator interface, this template generates a complete iterator that meets all of the requirements of a "bidirectional iterator" in the C++ standard. If T is const-qualified, then the resulting type is a constant iterator. T shall not be a function, reference type or void. ITER_IMP must provide public operations so that, for objects i and j of type ITER_IMP, the following operations are supported: ` ITER_IMP i; default construction ITER_IMP j(i); copy construction i = j assignment ++i increment to next element --i decrement to previous element i == j // convertible to bool equality comparison *i // reference convertible to T& element access (dereference) `
