    • processLocalOrNonConflictModification

      public void processLocalOrNonConflictModification(Csn csn, Modification mod)
      Description copied from class: AttrHistorical
      This method calculates the historical information and update the hist attribute to store the historical information for modify operation that does not conflict with previous operation. This is the usual path and should therefore be optimized.

      It does not check if the operation to process is conflicting or not with previous operations. The caller is responsible for this.

      Specified by:
      processLocalOrNonConflictModification in class AttrHistorical
      Parameters:
      csn - The CSN of the operation to process
      mod - The modify operation to process.

    • replayOperation

      public Modification replayOperation(Csn csn, Entry modifiedEntry, Modification mod)
      Description copied from class: AttrHistorical
      This method will be called when replaying an operation. It should use whatever historical information is stored in this class to solve the conflict and return the modification that will actually have to be replayed.
      Specified by:
      replayOperation in class AttrHistorical
      Parameters:
      csn - The CSN associated to the operation.
      modifiedEntry - The entry modified by this operation.
      mod - The modification.
      Returns:
      The modification which should be replayed, or null if the modification should not be replayed.
