Constructor & Destructor Documentation

filesystem_hard_link_write()

libdar::filesystem_hard_link_write::filesystem_hard_link_write ( const std::shared_ptr< user_interaction > &  dialog )

inline

Definition at line 63 of file filesystem_hard_link_write.hpp.

Member Function Documentation

clear_corres_if_pointing_to()

void libdar::filesystem_hard_link_write::clear_corres_if_pointing_to	(	const infinint &	ligne,
		const std::string &	path
	)

forget everything about a hard link if the path used to build subsequent hard links is the one given in argument

Parameters

[in]	ligne	is the etiquette number for that hard link
[in]	path	if the internaly recorded path to build subsequent hard link to that inode is equal to path, forget everything about this hard linked inode

corres_reset()

void libdar::filesystem_hard_link_write::corres_reset ( )

inlineprotected

Definition at line 85 of file filesystem_hard_link_write.hpp.

known_etiquette()

bool libdar::filesystem_hard_link_write::known_etiquette

(

const infinint &

eti

)

Returns

true if an inode in filesystem has been seen for that hard linked inode

make_file()

void libdar::filesystem_hard_link_write::make_file ( const cat_nomme *  ref, const path &  ou  )

protected

generate inode or make a hard link on an already restored or existing inode.

Parameters

[in]	ref	object to restore in filesystem
[in]	ou	where to restore it

raw_clear_ea_set()

bool libdar::filesystem_hard_link_write::raw_clear_ea_set ( const cat_nomme *  e, const std::string &  path  )

protected

remove EA set from filesystem's file, allows subsequent raw_set_ea

Parameters

[in]	e	this object may be a hard link to or an inode
[in]	path	the path in the filesystem where reside the object whose EA to clear

Returns

true if EA could be cleared, false if "e" is a hard link to an inode that has its EA already restored previously

raw_set_ea()

bool libdar::filesystem_hard_link_write::raw_set_ea ( const cat_nomme *  e, const ea_attributs &  list_ea, const std::string &  spot, const mask &  ea_mask  )

protected

add the given EA matching the given mask to the file pointed to by "e" and spot

Parameters

[in]	e	may be an inode or a hard link to an inode,
[in]	list_ea	the list of EA to restore
[in]	spot	the path where to restore these EA (full path required, including the filename of 'e')
[in]	ea_mask	the EA entry to restore from the list_ea (other entries are ignored)

Returns

true if EA could be restored, false if "e" is a hard link to an inode that has its EA already restored previously

Note

the list_ea EA are restored to spot path, the object e is only here to validate that this operation has not already been done through another hard linked inode to that same inode
