C<typename F::Toutvalue> aff::func::util::mapvalues	(	const typename C< typename F::Tinvalue >::Tcoc &	c,
		const F &	exfun
	)

Function template to map values from one container to another

This is a framework to browse through a container and map values to values of a different type. This function template is used by container functions like aff::func::valmap().

Parameters

C	any container class like aff::Array
F	any mapper utility class like aff::func::util::Mapvalmap
c	container to read values to be mapped
exfun	fully initialized mapper utility

Returns

result container of same shape as c but with mapped values
