class DiffOperation extends TargetOperation
deprecated
since version 2.8, to be removed in 3.0. Use TargetOperation instead.Diff operation between two catalogues.
The name of 'Diff' is misleading because the operation has nothing to do with diff:
intersection = source ∩ target = {x: x ∈ source ∧ x ∈ target} all = intersection ∪ (target ∖ intersection) = target new = all ∖ source = {x: x ∈ target ∧ x ∉ source} obsolete = source ∖ all = source ∖ target = {x: x ∈ source ∧ x ∉ target}
