Detailed Description

template<class Derived>
class zyppng::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
