## Member Function Documentation

## apply_permutation()

virtual void libdar::data_dir::apply_permutation | ( | archive_num | src,
|  | archive_num | dst
| ) |  |

overridevirtual

Reimplemented from libdar::data_tree.

## check_order()

virtual bool libdar::data_dir::check_order | ( | user_interaction & | dialog,
|  | const path & | current_path,
|  | bool & | initial_warn
| ) |  | const

overridevirtual

check date order between archives withing the database ; throw Erange if problem found with date order

Reimplemented from libdar::data_tree.

Referenced by libdar::database::i_database::check_order().

## compute_most_recent_stats()

virtual void libdar::data_dir::compute_most_recent_stats | ( | std::deque< infinint > & | data,
|  | std::deque< infinint > & | ea,
|  | std::deque< infinint > & | total_data,
|  | std::deque< infinint > & | total_ea
| ) |  | const

overridevirtual

Reimplemented from libdar::data_tree.

## 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.

## dump()

virtual void libdar::data_dir::dump | ( | generic_file & | f | ) | const

overridevirtual

Reimplemented from libdar::data_tree.

## finalize()

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

overridevirtual

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.

Reimplemented from libdar::data_tree.

## fix_corruption()

virtual bool libdar::data_dir::fix_corruption | ( |  | ) |

overridevirtual

Reimplemented from libdar::data_tree.

## obj_signature()

virtual char libdar::data_dir::obj_signature | ( |  | ) | const

inlineoverridevirtual

Reimplemented from libdar::data_tree.

Definition at line 91 of file data_dir.hpp.

## operator=()

data_dir & libdar::data_dir::operator= | ( | const data_dir & | ref | ) |

inline

## remove_all_from()

virtual bool libdar::data_dir::remove_all_from | ( | const archive_num & | archive_to_remove,
|  | const archive_num & | last_archive
| ) |  |

overridevirtual

return true if the corresponding file is no more located in any archive (thus, the object is no more usefull in the base)

Reimplemented from libdar::data_tree.

## signature()

static char libdar::data_dir::signature | ( |  | ) |

inlinestatic

Definition at line 92 of file data_dir.hpp.

## skip_out()

virtual void libdar::data_dir::skip_out | ( | archive_num | num | ) |

overridevirtual

decrement archive numbers above num

Reimplemented from libdar::data_tree.
