Description

UsesAllocatorArgT<t_TYPE volatile>

Trait metafunction that determines whether the constructor of t_TYPE can be invoked using bsl::allocator_arg as its first argument and an allocator object as its second argument. The value is computed by stripping off the cv‐qualifier and forwading to UsesAllocatorArgT<t_TYPE>, which is user‐specialized for the appropriate types.

UsesAllocatorArgT<t_TYPE const>

Trait metafunction that determines whether the constructor of t_TYPE can be invoked using bsl::allocator_arg as its first argument and an allocator object as its second argument. The value is computed by stripping off the cv‐qualifier and forwading to UsesAllocatorArgT<t_TYPE>, which is user‐specialized for the appropriate types.

UsesAllocatorArgT<t_TYPE const volatile>

Trait metafunction that determines whether the constructor of t_TYPE can be invoked using bsl::allocator_arg as its first argument and an allocator object as its second argument. The value is computed by stripping off the cv‐qualifier and forwading to UsesAllocatorArgT<t_TYPE>, which is user‐specialized for the appropriate types.
