Defines the frame boundaries, from start
(inclusive) to end
(inclusive).
Both start
and end
are relative from the current row. For example, "0" means "current row",
while "-1" means one off before the current row, and "5" means the five off after the
current row.
boundary start, inclusive. The frame is unbounded if this is the minimum long value.
boundary end, inclusive. The frame is unbounded if this is the maximum long value.
