Detailed Description

template<class Tp, class TUnaryFunction>
class zypp::base::ValueTransform< Tp, TUnaryFunction >

Helper managing raw values with transformed representation.

This helper enforces to explicitly state whether you are using the raw or the variable replaced value. Usually you set raw and get transformed (unless writing raw to some config file).

Used e.g. vor variable replaced config strings.
