Constructor Details

#initialize(mapping, removals: nil) ⇒ FileTransfer

Initializes a new FileTransfer instance

Parameters:

  • the mapping object containing source, destination, force, and ignore details

  • (defaults to: nil)

    pre-computed absolute paths to remove in force mode. When provided (from cached diff), skips the destination tree traversal in cleanup_folder. When nil, falls back to scanning the destination tree (used by backup transfers).
