## 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.

## 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.

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.
