Detailed Description

template<typename K_, typename V_>
class paludis::NamedValue< K_, V_ >

A NamedValue is used to hold a member of type V_ for a class.

NamedValue is used to simplify 'plain old data' style classes, and to provide compiler-time-checked named parameters for functions. Use thestruct.themember() and thestruct.themember() = to access the real underlying values.

Usually a struct containing NamedValue objects will be constructed using the make_named_values() function. For each NamedValue object, make_named_values() takes a parameter in the form n::whatever_K_is() = the_value.

In all cases, NamedValue members are listed in name-sorted order, and the same name is used for K_ and the member name.
