8 | /*This class is an interface between the altro format file and the |
9 | user, and can be used in write or read mode |
10 | In the write mode a new altro file is created and filled using the method FillBuffer(). |
11 | The name of the file is specified as parameter in the constructor as well as the type mode. |
12 | In the Read mode the specified file is open and the values can be read using the |
13 | methods GetNext() and GetNextBackWord(). |
14 | The first method is used to read the file forward while the second is used to read backward |
