Detailed Description

template<class TYPES>
class bdlb::VariantImp_NoAllocatorBase< TYPES >

This class is component-private. Do not use. This class contains the typedefs and data members of the Variant class, and serves as the base class for the variant when none of the types held by the variant has the bslma::UsesBslmaAllocator type trait. The goal is to optimize the size of the variant to avoid holding an unnecessary allocator pointer.

See Component bdlb_variant
