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.

◆ 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()

◆ 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.
