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  )

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.
