CXB_MULTIPLE_STRING

Class CXB_MULTIPLE_STRING manages multilingual character strings:

 
class CXB_MULTIPLE_STRING 
{ public: 
         CXB_MULTIPLE_STRING(void); 
         CXB_MULTIPLE_STRING(CXB_MULTIPLE_STRING &); 
         ˜CXB_MULTIPLE_STRING(void); 
 
         inline operator char *() { return GetString();  } 
         int operator&(char *); 
 
         char *GetString(void); 
         char *GetString(int k); 
         inline int N(void) 
         { return n; 
         } 
         int NTrue(void); 
         void Import(char *, int); 
         CXB_MULTIPLE_STRING &operator=(CXB_MULTIPLE_STRING &); 
         CXB_MULTIPLE_STRING &operator=(CXB_STRING &); 
         CXB_MULTIPLE_STRING &operator=(char *); 
         CXB_MULTIPLE_STRING &operator|=(char *); 
         CXB_MULTIPLE_STRING &operator+=(char); 
         CXB_MULTIPLE_STRING &operator+=(char *); 
         CXB_MULTIPLE_STRING &operator+=(CXB_STRING &); 
         CXB_MULTIPLE_STRING &operator+=(CXB_MULTIPLE_STRING &); 
         inline char *operator[](int i) 
         { return GetString(i);   } 
 
  private: 
         unsigned char n;  // number of strings held at the moment 
         unsigned char g;  // g slots allocated (g = m * GRANULARITY, 
                           //                        m = 1, 2, ...) 
         CXB_STRING **str; // slots holding the strings 
}; 

Since the operator (char *) has been overloaded, objects of this class can be used like ordinary strings of the type 'char *'. You get the character string corresponding to the current language (see CXB_SYSTEM). Further operations are shown in the following table:

Operator Function	Meaning
(char *)	Character string in current language (CXB_SYSTEM)
i	Character string in the i-th language
=	Assignment: a single character string (type 'char *' or 'CXB_STRING') overwrites the character string belonging to the current language
|=	imports the string as n+1-th string
+=	concatenation, for a single character string with the string belonging to the current language
&	TRUE - String exists in object
N()	get the number of strings (languages)
NTrue()	TRUE - at least one character string > " " exists
