Detailed Description

template<class Derived>
class zypp::IdStringType< Derived >

Base class for creating IdString based types.

Just by deriving from IdStringType a class provides all the operations an IdString does. (incl. conversion to string types, comparison of string types and stream output).

To disable any comparison, declare (but do not define) _doCompare in your class. 

 class NoCompare : public IdStringType<NoCompare>
 {
   private:
   static int _doCompare( const char * lhs,  const char * rhs );

 };

If you need a different than the default lexicographical order, write your own _doCompare.

    // uses default lexicographical order
    class CaseCmp : public IdStringType<CaseCmp>
    {
      public:
        CaseCmp() {}
        explicit CaseCmp( const char * cstr_r ) : _str( cstr_r )  {}
      private:
        friend class IdStringType<CaseCmp>;
        IdString _str;
    };

    // uses case insensitive comparison order
    class NoCaseCmp : public IdStringType<NoCaseCmp>
    {
      public:
        NoCaseCmp() {}
        explicit NoCaseCmp( const char * cstr_r ) : _str( cstr_r )  {}
      private:
        static int _doCompare( const char * lhs,  const char * rhs )
        {
          if ( lhs == rhs ) return 0;
          if ( lhs && rhs ) return ::strcasecmp( lhs, rhs );
          return( lhs ? 1 : -1 );
        }
      private:
        friend class IdStringType<NoCaseCmp>;
        IdString _str;
    };

    CaseCmp   ca( "a" );
    NoCaseCmp na( "a" );
    DBG << "ca == a ? " << (ca == "a") << endl;   // ca == a ? 1
    DBG << "ca == A ? " << (ca == "A") << endl;   // ca == A ? 0
    DBG << "na == a ? " << (na == "a") << endl;   // na == a ? 1
    DBG << "na == A ? " << (na == "A") << endl;   // na == A ? 1
Todo:
allow redefinition of order vis _doCompare not only for char* but on any level
