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.

Definition at line 81 of file database5.hpp.

Member Function Documentation

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.

show_most_recent_stats()

void libdar5::database::show_most_recent_stats

(

user_interaction &

dialog

)

const

compute some statistics about the location of most recent file versions

Parameters

[in]

dialog

where to display the listing to

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.
