template<>
DRN_FOUNDATION_EXPORT std::ostream &	operator<< (std::ostream &out, const std::optional<::QString > &opt)
	Full object stream insertion operator.

Detailed Description

STL namespace.

Function Documentation

◆ operator<<() [1/2]

template<typename ValueType>

std::ostream & std::operator<<	(	std::ostream &	out,
		const std::optional< ValueType > &	opt )

Full object stream insertion operator.

Note: There is potential here for undefined behaviour, but the risk is worth taking to have a uniform way of outputting an optional value.

Template Parameters

ValueType The type to place into the stream. This must have support for a stream insertion operator.

Parameters

out	The stream to place the data into.
opt	The data to place into the stream.

Returns: The modified stream after insertion.

◆ operator<<() [2/2]

template<>

DRN_FOUNDATION_EXPORT std::ostream & std::operator<<	(	std::ostream &	out,
		const std::optional<::QString > &	opt )
