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
