void AlterTableHandler::RemoveFieldAction::simplifyActions (  ActionDictDict &  fieldActions  )  [virtual]

Legend: A,B==objects, P==property, [....]==action, (..,..,..) group of actions, <...> internal operation. Preconditions: we assume there cannot be such case encountered: ([remove A], [do something related on A]) (except for [remove A], [insert A]) General Case: it's safe to always insert a [remove A] action.
