#empty? ⇒ Boolean

Note:

it assumes that:

  1. renames go before moving nodes
  2. moving nodes does not include a rename
  3. moving nodes includes all the path on both, source and destination tags
Note:

DISABLED: the order should be that in what the operations happened! An important thing is that all the path is always included in the mappings.

  • The only way that this would work is to apply upper (previous) tags_maps to subsequent ones. But the order should still be kept!

Sorts the maps in the correct order def sorted_maps [].tap do |sorted| src_maps.each do |curr_map| pos = nil sorted.each_with_index.reverse_each do |prev_map, idx| pos = idx + 1 if prev_map.goes_before?(curr_map) break if pos end sorted.insert(pos || 0, curr_map) end end end

Returns:

  • (Boolean)
