bsl::allocator_traits<allocator<TYPE>>

Synopsis

Declared in <bslma_bslallocator.h>

template<class TYPE>
struct allocator_traits<allocator<TYPE>>;

Description

This struct template provides a specialization of the allocator_traits class template for bsl::allocator. This specialization is not strictly necessary, but its presence speeds up compliation by bypassing a significant amount of metaprogramming.
