43 // <synopsis>
44 // This class is a specialization of the abstract base class
45 // <linkto class=DataConversion>DataConversion</linkto>.
46 // It contains functions to convert data from/to the Modcomp format
47 // using the static functions in class <linkto class=ModcompConversion>
48 // ModcompConversion</linkto>.
49 // </synopsis>
50 
51 // <example>
52 // See example in class <linkto class=DataConversion>DataConversion</linkto>.
53 // </example>
54 
55 // <motivation>
56 // This class is an addition to <linkto class=ModcompConversion>
57 // ModcompConversion</linkto>
58 // to be able to use the conversion functions in a polymorphic way.
