I recently had to use Boost Iterator Facade and its relatives and found the idea great. It occured to me whiel lookign at my X different, hand written allocaotrs for various project that maybe such a system for writing std allocator could be great. Buildign a new allcoator will just be impelemnt some allocator_facade<> adn fill some small scale methods.
Moreover, it could be the opportunity to add new allocator concept like allocator supporting resize calls, allcoator with state, allcoator with a allocated() method etc... and reality-check them in the boost framework.
How does it sounds ?
Sounds great! I've had the same experience. Writing an iterator using the iterator facade is fun. You can concentrate on the essentials. Writing an allocator, on the other hand, you write so much additional stuff. I have an allocator that uses mmap for each allocation. The file has little over 100 lines. But only two of them are actually doing something. The rest is just stuff required for stl allocators... So, yeah, an allocator facade would be cool! Regards, Roland
