Detailed Description

template<class ALLOC>
struct bslma::AllocatorTraits_HasIsAlwaysEqual< ALLOC >

This struct template provides a mechanism for determining whether a given (template parameter) ALLOCATOR_TYPE defines a nested alias named is_always_equal. The static boolean member value (nested alias named type) is true (bsl::true_type) if ALLOCATOR_TYPE defines such an alias, and false (bsl::false_type) otherwise.
