java.lang.Object

org.apache.flink.table.runtime.operators.over.frame.UnboundedFollowingOverFrame

org.apache.flink.table.runtime.operators.over.frame.RowUnboundedFollowingOverFrame

所有已实现的接口:

Serializable, OverWindowFrame

public class RowUnboundedFollowingOverFrame
extends UnboundedFollowingOverFrame

The row unboundedFollowing window frame calculates frames with the following SQL form: ... ROW BETWEEN [window frame preceding] AND UNBOUNDED FOLLOWING [window frame preceding] ::= [unsigned_value_specification] PRECEDING | CURRENT ROW

e.g.: ... ROW BETWEEN 1 PRECEDING AND UNBOUNDED FOLLOWING.
