  • Field Details

    • MARK

      public static final FlowControlOperation MARK
      Stores the current datarow state for a later recall. Markpoints from different sources can be nested. Marking does not change the user datasource.
    • ADVANCE

      public static final FlowControlOperation ADVANCE
      Requests that the datasource should be moved to the next row. An advance operation does not change the current cursor position. The cursor is not moved until a 'COMMIT' operation has been reached. Repeatable sections will perform an auto-commit based on the group in which they are in.
    • RECALL

      public static final FlowControlOperation RECALL
      Recalls a marked position.
    • NO_OP

      public static final FlowControlOperation NO_OP
      Do nothing.
    • DONE

      public static final FlowControlOperation DONE
      Finishes (and closes) the currently open context. If the last mark has been closed, the datasource is also closed.

      If all datasources have been closes, the empty datasource is used. This datasource cannot be closed (closing has no effect on it).

    • COMMIT

      public static final FlowControlOperation COMMIT
      A commit checks for an pending advance request and commites that request by moving the cursor of the currend datarow forward by one row.
