Description

ConstructionUtil_AllocAdaptorUtil<TYPE, false, false>

This utility class template provides a static adapt method that adapts an allocator object to the type expected by TYPE. This primary template is instantiated only for a non‐AA TYPE; such types do not expect an allocator, so no adapt method is defined.

ConstructionUtil_AllocAdaptorUtil<TYPE, false, true>

This utility class template provides a static adapt method that adapts an allocator object to the type expected by TYPE. This partial specialization is instantiated for types that expect an allocator of type bslma::Allocator *.

ConstructionUtil_AllocAdaptorUtil<TYPE, true, IS_BSLMA_AA>

This utility class template provides a static adapt method that adapts an allocator object to the type expected by TYPE. This partial specialization is instantiated for types that expect an allocator of type TYPE::allocator_type.
