| Name| Description
| xref:BloombergLP/bslstl/Variant_CopyAssignVisitor/2constructor.adoc[`Variant_CopyAssignVisitor`]         [.small]#[constructor]#
| Create a `Variant_CopyAssignVisitor` object that, when invoked, will copy‐assign to the active alternative of the specified `variant`.
| xref:BloombergLP/bslstl/Variant_CopyAssignVisitor/operator_call.adoc[`operator()`] 
| Copy‐assign to the active alternative of `*d_variant_p` from the specified `value` (i.e. the alternative that is being visited). The behavior is undefined unless (template parameter) `t_INDEX` is the index of the active alternative of `*d_variant_p` (or, in C++03, the index of an alternative that has the same type as the active alternative).
