stream_operator()

template<typename T >

auto stream_operator	(	std::ostream &	stream,
		const iox2::bb::Optional< T > &	value
	)		-> std::ostream&

A custom stream operator implementation. The default operator<< cannot be used since the optional can be exchanged with a customer based implementation that may already come with a stream operator implementation.
