this is the interface class from which all other data transfer classes inherit
the arbitrary large positive integer class
the generic class, parent of all masks
Definition mask.hpp:62
switch module to limitint (32 ou 64 bits integers) or infinint
here lies a collection of mask classes
include macro defined by the configure script and some specific additional ones
