## set_slice_min_digits()

void libdar::archive_options_merge::set_slice_min_digits | ( | infinint | val | ) |

inline

defines the minimum digit a slice must have concerning its number, zeros will be prepended as much as necessary to respect this

Definition at line 1165 of file archive_options.hpp.

## set_slicing()

void libdar::archive_options_merge::set_slicing | ( | const infinint & | file_size,
|  | const infinint & | first_file_size = 0 )

inline

define the archive slicing

Parameters

  [in] | file_size | set the slice size in byte (0 for a single slice whatever its size is)
  [in] | first_file_size | set the first file size

Note
  if not specified or set to zero, first_file_size is considered equal to file_size

Definition at line 1177 of file archive_options.hpp.

## set_subtree()

void libdar::archive_options_merge::set_subtree | ( | const mask & | subtree | ) |

defines the directories and files to consider

Note
  WARNING: The filter mechanism used here is common to all operations and works by comparing full paths, while in the other hand, paths stored in the libdar archive are all relative to what was provided as fs_root at backup time. To have this filter mecanism working in the context of merging, where no fs_root can be provided to transform relative paths to absolute paths, libdar will emulate an fs_root with the pseudo root value of the path::FAKE_ROOT field. This is invisible form the libdar API user except when relying on mask_list objects, which cannot thus receive full path as those would not be prepended by path::FAKE_ROOT as fs_root value, because fs_root prefixing is only performed for relative paths.

## set_user_comment()

void libdar::archive_options_merge::set_user_comment | ( | const std::string & | comment | ) |
