## Detailed Description

the data_dir class inherits from data_tree and holds the directory tree's parent relationship

Definition at line 52 of file data_dir.hpp.

## Member Function Documentation

## ◆ data_tree_find()

bool libdar::data_dir::data_tree_find | ( | path | chemin,
|  | const data_tree *& | ptr
| ) |  | const

lookup routine to find a pointer to the dat_tree object corresponding to the given path

Parameters

  [in] | chemin | is the path to look for
  [out] | ptr | is a pointer to the looked node, if found

Returns
  true if a node could be found in the database

## ◆ data_tree_read()

static data_dir* libdar::data_dir::data_tree_read | ( | generic_file & | f,
|  | unsigned char | db_version
| ) |  |
| static

read a signature and then run the data_dir constructor but aborts if not a data_dir

Note
  the constructors of data_tree and data_dir do not read the signature because its purpose it to know whether the following is a data_dir or data_tree dump() result.

## ◆ finalize()

virtual void libdar::data_dir::finalize | ( | const archive_num & | archive,
|  | const datetime & | deleted_date,
|  | const archive_num & | ignore_archive_greater_or_equal
| ) |  |
| override virtual

add deleted entry if no object of the current archive exist and the entry of the previous archive is already present.

Parameters

  [in] | archive | is the number of the archive to finalize
  [in] | deleted_date | date of deletion to use for inode removal when no information can be grabbed from the archive (this date is taken from the parent dir last modification date)
  [in] | ignore_archive_greater_or_equal | ignore archives which number is greater or equal than "ignore_archive_greater_or_equal" as if they were not present in the database. If set to zero, no archive is ignored.
