Detailed Description

template<class _Tp>
class zypp::KindOf< _Tp >

Maintain string values representing different kinds of a type.

Example: We have different kinds of Resolvable: Package, Patch, etc. We want some thing to identify these types and have a string value associated. Identification should be constructible from this string. An Enumeration Class could do this, but we would also like to be extensible at runtime.

KindOf stores a lowercased version of a string and uses this as identification.

Todo:

Unify strings and associate numerical value for more efficient comparison and use in switch.

Todo:

Make lowercased/uppercased/etc an option. First of all get rid of the string::toLower calls operator.

Todo:

Maybe collaboration with some sort of Registry.
