Results of performing recovery.

Responses to whether or not the instance is recoverable.

If we don't have an XAResource then we cannot recover at this stage. The XAResource will have to be provided for us and then we can retry. Because recovery happens periodically, it is possible that it takes a snapshot of a transaction that is still running and will vanish from the log anyway. If that happens, then we don't need to (and can't) run recovery on it.
    public int recoverable ();

    
Attempt the recovery. Return one of the status values above.
    public int recover ();

    

Returns:
the Xid that was used to manipulate this state.
    public Xid getXid ();

    

Returns:
the Uid for this instance.
    public Uid get_uid ();

    

Returns:
the type for this instance.
    public String type ();
