## Detailed Description

keep trace of already written inodes to restore hard links

Definition at line 57 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

## ◆ 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
