Detailed Description

template<typename TYPE>
class original::doubleDirectionIterator< TYPE >

Abstract base class for double-direction iterators.

Template Parameters

TYPE	Type of elements being iterated

Implements core functionality for iterators that can traverse elements in both directions (forward and backward) with single-step movements. This class extends the stepIterator and provides support for both forward and backward iteration.
