This component-private struct computes an array in which element i is a pointer to Variant_Function<t_RET, t_VISITOR, t_VARIANT, i>::functionImpl.

struct Variant_VTable;The referenced function invokes a t_VISITOR with alternative i of t_VARIANT and implicitly converts the return type to t_RET.
| Name | Description |
|---|---|
Variant_VTable<t_RET, t_VISITOR, t_VARIANT, bslmf::IntegerSequence<std::size_t, t_INDICES...>> | This partial specialization provides the actual s_map array once t_DUMMY is deduced as an IntegerSequence of alternative indices. |
