## Detailed Description

the database class defines the dar_manager database

all operations for a dar_manager database are defines through the use of this class interface. This class also defines internally the data structure of the database.

Definition at line 81 of file database5.hpp.

## Member Function Documentation

## ◆ show_contents()

void libdar5::database::show_contents | ( | user_interaction & | dialog | ) | const

show the list of archive used to build the database

Parameters

  [in,out] | dialog | is the user_interaction to use to report the listing

## ◆ show_files()

void libdar5::database::show_files | ( | user_interaction & | dialog,
|  | archive_num | num,
|  | const database_used_options & | opt
| ) |  | const

list files which are present in a given archive

Parameters

  [in,out] | dialog | where to display listing to
  [in] | num | is the archive number to look at
  [in] | opt | optional parameters for this operation

Note
  if "num" is set to zero all archive contents is listed
  this method is not available with partially extracted databases.

## ◆ show_most_recent_stats()

void libdar5::database::show_most_recent_stats | ( | user_interaction & | dialog | ) | const

compute some statistics about the location of most recent file versions

Parameters

  [in] | dialog | where to display the listing to

Note
  this method is not available with partially extracted databases.

## ◆ show_version()

void libdar5::database::show_version | ( | user_interaction & | dialog,
|  | path | chemin
| ) |  | const

list the archive where a give file is present

Parameters

  [in,out] | dialog | where to display the listing to
  [in] | chemin | path to the file to look for

Note
  this method is not available with partially extracted databases.
