Synopsis

This class is intended to be used as a common class for all classes converting data to/from little-endian format.

Motivation

Sometimes data are stored in little-endian format (e.g. old VAX-data). Instead of putting all these conversion functions in all such classes, it is better to keep them separate to be able to use them elsewhere. However, note that this version handles a long as 4 bytes. On several little-endian machines (e.g. DEC-alpha) a long is 8 bytes, so a special function is needed for them.

To Do

  • Support data type long double.
  • Support a long as 4 or as 8 bytes.
