Detailed Description

CRTP Mixins for container functionality (DRY principle).

This file provides CRTP (Curiously Recurring Template Pattern) mixin classes that implement common container operations. These mixins replace the macro-based approach in ahDry.H with properly documented, type-safe template classes.

Usage

To use these mixins, inherit from them using CRTP:

template <typename T>
class MyContainer : public TraverseMixin<MyContainer<T>, T>,
                    public FunctionalMixin<MyContainer<T>, T>,
                    public LocateMixin<MyContainer<T>, T>
{
  // Your container implementation
  // Must provide: get_it(), Iterator with has_curr(), get_curr(), next_ne()
};

Requirements

The derived class must provide:

• Iterator nested type with:
  • has_curr() - returns true if iterator points to valid element
  • get_curr() - returns reference to current element
  • next_ne() - advances to next element (no exception version)
• get_it() - returns an Iterator positioned at the first element
