A row containing a null in the timestamp column belongs to no window and will not have a value computed or be considered in the windows of other rows.
  
  Parameters:
  
  timestampCol - the name of the timestamp column
  
  revTime - the look-behind window size (in nanoseconds)
  
  fwdTime - the look-ahead window size (in nanoseconds)
  
  pairs - The input/output column name pairs
  
  Returns:

- RollingMax
  
  static UpdateByOperation RollingMax(long revTicks, String... pairs)
  
  Create a rolling maximum for the supplied column name pairs, using ticks as the windowing unit. Ticks are row counts and you may specify the previous window in number of rows to include. The current row is considered to belong to the reverse window, so calling this with revTicks = 1 will simply return the current row. Specifying revTicks = 10 will include the previous 9 rows to this one and this row for a total of 10 rows.
  
  Parameters:
  
  revTicks - the look-behind window size (in rows/ticks)
  
  pairs - The input/output column name pairs
  
  Returns:

Negative values are allowed and can be used to generate completely forward or completely reverse windows. A row containing a null in the timestamp column belongs to no window and will not have a value computed or be considered in the windows of other rows.
  Here are some examples of window values:
  
  revDuration = 0m, fwdDuration = 0m - contains rows that exactly match the current row timestamp
  
  revDuration = 10m, fwdDuration = 0m - contains rows from 10m earlier through the current row timestamp (inclusive)
  
  revDuration = 0m, fwdDuration = 10m - contains rows from the current row through 10m following the current row timestamp (inclusive)
  
  revDuration = 10m, fwdDuration = 10m - contains rows from 10m earlier through 10m following the current row timestamp (inclusive)
  
  revDuration = 10m, fwdDuration = -5m - contains rows from 10m earlier through 5m before the current row timestamp (inclusive), this is a purely backwards looking window
  
  revDuration = -5m, fwdDuration = 10m - contains rows from 5m following through 10m following the current row timestamp (inclusive), this is a purely forwards looking window
  Parameters:
  
  timestampCol - the name of the timestamp column
  
  revDuration - the look-behind window size (in Duration)
  
  fwdDuration - the look-ahead window size (in Duration)
  
  pairs - The input/output column name pairs
  
  Returns:
  
  The aggregation
- RollingWAvg
  
  static UpdateByOperation RollingWAvg(String timestampCol, long revTime, String weightCol, String... pairs)
  
  Create a rolling weighted average for the supplied column name pairs, using time as the windowing unit. This function accepts nanoseconds as the reverse window parameters. A row containing a null in the timestamp column belongs to no window and will not have a value computed or be considered in the windows of other rows.
  
  Parameters:
  
  timestampCol - the name of the timestamp column
  
  revTime - the look-behind window size (in nanoseconds)
  
  pairs - The input/output column name pairs
  
  Returns:
  
  The aggregation
- RollingWAvg
  
  static UpdateByOperation RollingWAvg(String timestampCol, long revTime, long fwdTime, String weightCol, String... pairs)
  
  Create a rolling weighted average for the supplied column name pairs, using time as the windowing unit. This function accepts nanoseconds as the reverse and forward window parameters. Negative values are allowed and can be used to generate completely forward or completely reverse windows. A row containing a null in the timestamp column belongs to no window and will not have a value computed or be considered in the windows of other rows.
  
  Parameters:
  
  timestampCol - the name of the timestamp column
  
  revTime - the look-behind window size (in nanoseconds)
  
  fwdTime - the look-ahead window size (in nanoseconds)
  
  pairs - The input/output column name pairs

  The aggregation
- RollingFormula
  
  static UpdateByOperation RollingFormula(long revTicks, String formula, String paramToken, String... pairs)
  
  Create a rolling forumla for the supplied column name pairs, using ticks as the windowing unit. Ticks are row counts and you may specify the previous window in number of rows to include. The current row is considered to belong to the reverse window, so calling this with revTicks = 1 will simply return the current row. Specifying revTicks = 10 will include the previous 9 rows to this one and this row for a total of 10 rows.
  Parameters:
  
  revTicks - the look-behind window size (in rows/ticks)
  
  formula - the user-defined formula to apply to each group. This formula can contain any combination of the following:
  
  Built-in functions such as min, max, etc.
  
  Mathematical arithmetic such as *, +, /, etc.
  
  User-defined functions
  
  paramToken - the parameter name for the input column's vector within the formula. If formula is max(each), then each is the formula_param.
  
  pairs - The input/output column name pairs
  
  Returns:
  
  The aggregation
- RollingFormula
  
  static UpdateByOperation RollingFormula(long revTicks, long fwdTicks, String formula, String paramToken, String... pairs)
  Create a rolling forumla for the supplied column name pairs, using ticks as the windowing unit. Ticks are row counts and you may specify the reverse and forward window in number of rows to include. The current row is considered to belong to the reverse window but not the forward window. Also, negative values are allowed and can be used to generate completely forward or completely reverse windows.
  Here are some examples of window values:
  
  revTicks = 1, fwdTicks = 0 - contains only the current row
  
  revTicks = 10, fwdTicks = 0 - contains 9 previous rows and the current row
  
  revTicks = 0, fwdTicks = 10 - contains the following 10 rows, excludes the current row
  
  revTicks = 10, fwdTicks = 10 - contains the previous 9 rows, the current row and the 10 rows following
  
  revTicks = 10, fwdTicks = -5 - contains 5 rows, beginning at 9 rows before, ending at 5 rows before the current row (inclusive)
  
  revTicks = 11, fwdTicks = -1 - contains 10 rows, beginning at 10 rows before, ending at 1 row before the current row (inclusive)
  
  revTicks = -5, fwdTicks = 10 - contains 5 rows, beginning 5 rows following, ending at 10 rows following the current row (inclusive)
  Parameters:
  
  revTicks - the look-behind window size (in rows/ticks)
  
  fwdTicks - the look-ahead window size (in rows/ticks)
  
  formula - the user-defined formula to apply to each group. This formula can contain any combination of the following:
  
  Built-in functions such as min, max, etc.
