Detailed Description

the contextual class adds the information of phases in the generic_file

several phases are defined like for example

• INIT phase
• OPERATIONAL phase
• LAST SLICE phase

these are used to help the command launched between slices to decide the action to do depending on the context when reading an archive (first slice / last slice read, ...) the context must also be transfered to dar_slave through the pair of tuyau objects

this class also support some additional informations common to all 'level1' layer of archive, such as:

• the data_name information

Member Function Documentation

get_data_name()

virtual const label& libdar::contextual::get_data_name ( ) const

pure virtual

obtain the data_name of the archive (label associated with the archive's data)

Note

label are conserved with dar_xform and archive isolation, but are not with archive merging or archive creation (full or differential backup)

Implemented in libdar::zapette, libdar::trontextual, libdar::trivial_sar, and libdar::sar.

set_info_status()

virtual void libdar::contextual::set_info_status ( const std::string &  s )

inlinevirtual

defines the new contextual value

Note

inherited class may redefine this call but but must call the parent method to set the value contextual:set_info_status()

Reimplemented in libdar::zapette.

Definition at line 88 of file contextual.hpp.
