All Implemented Interfaces:

Comparable<WindowAggregateOp>

public class WindowAggregateOp
extends Object
implements Comparable<WindowAggregateOp>

Operator for window-based aggregation (for analytical functions). It encapsulates the aggregation operation, and window-parameters. Note: An aggregation operation (e.g. SUM) specified with different window parameters (e.g. preceding-window = 5, vs preceding-window = 10) will be deemed as *distinct* window operations.
