template<typename 
Impl>
class zypp::detail::SimpleStreamBuf< Impl >
Implementation of a std::streambuf that is using a std::vector<char> as buffer, relies on a Impl class that must implement the basic i/o functionality:
class streambufimpl {
  public:
    using error_type = my_error_type;
 
    ~streambufimpl();
 
    bool isOpen   () const; 
    bool canRead  () const; 
    bool canWrite () const; 
    bool canSeek  ( std::ios_base::seekdir way_r ) const; 
 
    std::streamsize readData ( char * buffer_r, std::streamsize maxcount_r  ); 
    bool writeData( const char * buffer_r, std::streamsize count_r ); 
    off_t seekTo( off_t off_r, std::ios_base::seekdir way_r, std::ios_base::openmode omode_r ); 
    off_t tell() const; 
 
    error_type error() const; 
 
  protected:
    bool openImpl( const char * name_r, std::ios_base::openmode mode_r ); 
    bool closeImpl ();  
};
- Note
- Currently only supports reading or writing at the same time, but can be extended to support both
