  • Constructor Details

    • MinMaxAggWindow

      public MinMaxAggWindow(long start, long end)

  • Method Details

    • hasMore

      public boolean hasMore(int level)

    • isMinFirst

      protected boolean isMinFirst()

    • getValue

      public HistoricalValue getValue(int level)
      Description copied from interface: DataWindow
      Returns the value for the specified "level" of the window. Windows generally only have one value, but technically they are allowed to have any number. As long as hasMore is true, this function will be called with an incremented level.

    • getEntryValue

      public HistoricalValue getEntryValue()
      Description copied from interface: DataWindow
      Returns the edge value of the window, which will be used for interpolation from the previous value. This value is not necessarily returned from the getValue() function as part of the window itself.

    • getExitValue

      public HistoricalValue getExitValue()
      Description copied from interface: DataWindow
      Returns the "exit" value of this window. Generally this will be the same as getValue(x) with x=the highest level provided by the window, but sometimes it could be the last received raw value. Interpolation will occur between this value and the entry value of the next window.

    • initialize

      public void initialize(HistoricalValue entryValue)
      Description copied from interface: DataWindow
      Provides the window with the previous window's value. May not be used by all window types.

    • finalize

      public void finalize(HistoricalValue trailingValue)
      Description copied from interface: DataWindow
      Provides the window with the value that comes next, outside of the window, in order to finalize calculations. May not be used by all window types.

    • addValue

      public void addValue(HistoricalValue value)
      Description copied from interface: DataWindow
      Adds a value to the window.

    • isMin

      protected boolean isMin(HistoricalValue val)

    • isMax

      protected boolean isMax(HistoricalValue val)

    • isEntry

      protected boolean isEntry(HistoricalValue val)

    • isLatest

      protected boolean isLatest(HistoricalValue val)
