trontextual class is a contextual class tronc, that&#39;s all.
Definition: trontextual.hpp:40
switch module to limitint (32 ou 64 bits integers) or infinint
this is the interface class from which all other data transfer classes inherit
the arbitrary large positive integer class
makes a segment of a generic_file appear like a real generic_file
