    • isLastExcluded

      public boolean isLastExcluded()
      Is the last excluded index still excluded, or has it been included by a later operation?

    • isLastIncluded

      public boolean isLastIncluded()
      Is the last included index still included, or has it been excluded by a later operation?

    • pivot

    • resetHistory

      public void resetHistory()
      After bulk operations, like setting up some initial state, the history of last included and excluded is probably not relevant. It may be a good idea to reset it to prevent it from affecting following logic.
