      See Also:

    • topLevelOnePhaseCommit

      public int topLevelOnePhaseCommit()
      For commit_one_phase we can do whatever we want since the transaction outcome is whatever we want. Therefore, we do not need to save any additional recoverable state, such as a reference to the transaction coordinator, since it will not have an intentions list anyway.
      Overrides:
      topLevelOnePhaseCommit in class AbstractRecord
      Returns:
      TwoPhaseOutcome to indicate success/failure.
      See Also:

    • save_state

      public boolean save_state(OutputObjectState os, int t)
      Description copied from class: AbstractRecord
      When the transaction is required to make the intentions list persistent, it scans the list and asks each record whether or not it requires state to be saved (by calling doSave). If the answer is yes, then save_state is called and the record instance must save enough information to enable it to be restored from that state later. The basic AbstractRecord save_state will save common data that is required by the base class during recovery. If a derived class calls super.save_state then it must be called before packing any other data item.
      Overrides:
      save_state in class AbstractRecord
      Returns:
      true if successful, false otherwise.

    • restore_state

      public boolean restore_state(InputObjectState os, int t)
      Description copied from class: AbstractRecord
      During recovery, the transaction log is given to the recovery system and it will recreate a transaction instance to perform necessary recovery actions. This transaction will recreate the intentions list and give each recreated AbstractRecord the state that that was saved during transaction persistence. The base class will restore information that it needs from the log. Data items must be unpacked in the same order that they were packed.
      Overrides:
      restore_state in class AbstractRecord
      Returns:
      true if successful, false otherwise.

    • type

      public String type()
      Description copied from class: AbstractRecord
      Re-implementation of abstract methods inherited from base class.
      Overrides:
      type in class AbstractRecord

    • typeName

      public static String typeName()

    • doSave

      public boolean doSave()
      Description copied from class: AbstractRecord
      Should this record be saved in the intentions list? If the record is saved, then it may be recovered later in the event of a failure. Note, however, that the size of the intentions list on disk is critical to the performance of the system (disk I/O is a bottleneck).
      Overrides:
      doSave in class AbstractRecord
      Returns:
      true if it should be saved, false otherwise. false is the default.

    • merge
