| destructor
std::vector< std::string > | getSubStreamList (unsigned ind=0, bool all=false)
| function to retrieve the list of actual direntry
void | setRevision (unsigned rev)
| set the OLE revision
void | setRootType (bool pc)
| set the root to a mac/pc root *‍/
bool | addStream (std::string const &name, unsigned char const *buffer, unsigned long len)
| add a new stream knowing its data
bool | addDirectory (std::string const &dir)

DirEntry * | createEntry (std::string const &name)
| return a new dir entry, if it does not exists
bool | updateToSave ()
| finish to update the file ( note: it is better to call this function only one time )
