tronc.hpp
defines a limited segment over another generic_file.
libdar::label
manage label data structure used in archive slice headers
Definition: label.hpp:42
contextual.hpp
class contextual adds the information of phases in the generic_file
libdar::gf_mode
gf_mode
generic_file openning modes
Definition: gf_mode.hpp:43
libdar::tronc
makes a segment of a generic_file appear like a real generic_file
Definition: tronc.hpp:43
infinint.hpp
switch module to limitint (32 ou 64 bits integers) or infinint
libdar::infinint
the arbitrary large positive integer class
Definition: real_infinint.hpp:61
libdar::trontextual::get_data_name
virtual const label & get_data_name() const override
obtain the data_name of the archive (label associated with the archive's data)
Definition: trontextual.hpp:56
libdar::contextual::get_data_name
virtual const label & get_data_name() const =0
obtain the data_name of the archive (label associated with the archive's data)
libdar::trontextual::is_an_old_start_end_archive
virtual bool is_an_old_start_end_archive() const override
returns whether the archive is a old archive (format < 8)
Definition: trontextual.hpp:55
generic_file.hpp
class generic_file is defined here as well as class fichier
libdar::contextual::is_an_old_start_end_archive
virtual bool is_an_old_start_end_archive() const =0
returns whether the archive is a old archive (format < 8)
libdar::generic_file
this is the interface class from which all other data transfer classes inherit
Definition: generic_file.hpp:76
libdar::contextual
the contextual class adds the information of phases in the generic_file
Definition: contextual.hpp:73
libdar::trontextual
trontextual class is a contextual class tronc, that's all.
Definition: trontextual.hpp:44
libdar::trontextual::ref
contextual * ref
this is just a pointer to data owned by the inherited class tronc part of this object
Definition: trontextual.hpp:56
libdar
libdar namespace encapsulate all libdar symbols
Definition: archive.hpp:46
