UnboundedWindowFunctionFrame

final class UnboundedWindowFunctionFrame extends WindowFunctionFrame

The unbounded window frame calculates frames with the following SQL forms: ... (No Frame Definition) ... BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING

Its results are the same for each and every row in the partition. This class can be seen as a special case of a sliding window, but is optimized for the unbound case.
