BloombergLP::bdlb::Variant2::operator=

Assign the specified TYPE value to this object.

Synopsis

Declared in <bdlb_variant.h>

template<class TYPE>
Variant2<A1, A2>&
operator=(TYPE&& value)
requires !bsl::is_same<SelfType,
                      typename bsl::remove_cvref<TYPE>::type>::value;

Description

The contents of value are moved to this object with value left in a valid but unspecified state. The value currently held by this variant (if any) is destroyed if that value`s type is not the same as TYPE. TYPE must be the same as one of the types that this variant can hold. Note that in C++11 mode, this method does not participate in overload resolution if it would lead to ambiguity with the move‐assignment operator (below).

Return Value

reference providing modifiable access to this object

Parameters
