 public Transaction interface, in order to function correctly in
 the transactional editing domain framework.

| Method Summary | |
|---|---|
|  void | abort(IStatus status)Aborts the transaction with a reason given by the specified status. | 
|  void | add(Notification notification)Adds the specified notification to the list of notifications received during this transaction. | 
|  void | addTriggers(TriggerCommand triggers)Adds a group of triggers that were executed during my commit. | 
|  void | endPrivileged(PrivilegedRunnable<?> runnable)Returns me to my previous owner, upon completion of the specified privileged runnable. | 
|  List<Notification> | getNotifications()Obtains the list of notifications that were received during execution of this transaction. | 
|  InternalTransaction | getRoot()Obtains the root transaction (the one that has no parent). | 
|  Command | getTriggers()Obtains the triggers that were executed during my commit. | 
|  boolean | isRollingBack()Queries whether this transaction or any of its ancestors is in the process of rolling back. | 
|  void | pause()Pauses me while a child transaction is active, so that I do not collect either notifications or recorded changes during that time. | 
|  void | resume(TransactionChangeDescription nestedChanges)Resumes me after completion of a child transaction. | 
|  void | setParent(InternalTransaction parent)Assigns my parent transaction (the one in which I am nested). | 
|  void | setStatus(IStatus status)Sets the status of the transaction. | 
|  void | start()Starts me. | 
|  void | startPrivileged(PrivilegedRunnable<?> runnable)Transfers ownership of this transaction to the specified privileged runnable. |

InternalTransaction getRoot()
void setParent(InternalTransaction parent)
parent - my parent transaction
void start()
           throws InterruptedException
activate
 me.
 Note that this call should block the current thread until the editing domain grants exclusive access.
InterruptedException - if the current thread is interrupted while
     waiting for activationvoid abort(IStatus status)
status - a status object providing the reason.  It should be the status
     attached to the eventual RollbackException, and should be
     set as my statusvoid add(Notification notification)
notification - the notification to addgetNotifications()List<Notification> getNotifications()
add(Notification)void pause()
void resume(TransactionChangeDescription nestedChanges)
nestedChanges - the nested transaction's recorded changes, or
     null if it rolled back (in which case, I do not add
     anything to my changes)void setStatus(IStatus status)
status - my statusboolean isRollingBack()
true if I or my
   parent (if any) am rolling back;
   false otherwiseCommand getTriggers()
null if I have
     no triggers (perhaps because the Transaction.OPTION_NO_TRIGGERS
     was applied).  This may be a single Command or a
     compound of multiplevoid addTriggers(TriggerCommand triggers)
triggers - the triggers to addvoid startPrivileged(PrivilegedRunnable<?> runnable)
runnable - the runnable whose thread is to borrow mevoid endPrivileged(PrivilegedRunnable<?> runnable)
runnable - the runnable whose thread had borrowed me|
