to_string() [1/3]

template<typename Container , typename Callback , typename std::enable_if<!std::is_convertible< Callback, std::string >::value, int >::type = 0>

std::string mc_rtc::io::to_string	(	const Container &	c,
		Callback &&	get_value,
		const std::string &	delimiter = ", "
	)

Converts a container to a string

Example:

  const auto availabeRobots = mc_rtc::io::to_string(robots(), [](const mc_rbdyn::Robot & r) -> const std::string & {
*return r.name(); });

Template Parameters

Container

An iterable container whose unerlying type is convertible to std::string. The container must define Container::value_type.

Parameters

c	Container to convert
get_value	Lambda or functor that converts a single element from the container (of type Container::value_type) to std::string

Returns

A string of all the container elements.

to_string() [2/3]

template<typename Container , typename std::enable_if<!std::is_arithmetic< typename Container::value_type >::value, int >::type = 0>

std::string mc_rtc::io::to_string	(	const Container &	c,
		const std::string &	delimiter = ", "
	)

Converts a container to a string

Template Parameters

Container

A container whose underlying type is convertible to std::string. The container must define Container::value_type.

Parameters

c	Container to convert
delimiter	Separator between the elements. By default they are coma-separated

Returns

A string of all the container elements.

to_string() [3/3]

template<typename Container , typename std::enable_if< std::is_arithmetic< typename Container::value_type >::value, int >::type = 0>

std::string mc_rtc::io::to_string	(	const Container &	c,
		const std::string &	delimiter = ", ",
		const unsigned	precision = std::numeric_limits<typename Container::value_type>::digits10
	)

Variant of to_string that converts numeric types to string.

Parameters

precision

Number of digits to keep. The default precision corresponds to the number of decimal digits that can be represented without change.
