def compared_attrs
  @compared_attrs ||= []
end

#compared_attrs_when_present ⇒ Object

Note:

if present in one source but not in another, that attribute will NOT generate a diff.

Same as compared_attrs but they only get compared when present in both data sources

#key(value = nil) ⇒ String

Returns the attribute that is key of the node diff elements.

Parameters:

  • value (String, NilClass) (defaults to: nil)

Returns:

  • (String) —
