Abstract
A transactional adapter for an object-oriented data processing system maintains a tree of transactions corresponding to messages between objects. A message is transformed into a child transaction, but only when any access restrictions are met. Until then it is held in a “pending” set which is part of the parent transaction's state definition. When a child commits, its parent maintains the access restrictions imposed by the child if the parent is recoverable and discards them otherwise.
