public class StreamExecWindowAggregate
extends StreamExecWindowAggregateBase

Stream ExecNode for window table-valued based aggregate.

The differences between StreamExecWindowAggregate and StreamExecGroupWindowAggregate is that, this node is translated from window TVF syntax, but the other is from the legacy GROUP WINDOW FUNCTION syntax. In the long future, StreamExecGroupWindowAggregate will be dropped.

从类复制的说明: ExecNodeBase

Internal method, translates this node into a Flink operator.

指定者:

translateToPlanInternal 在类中 ExecNodeBase<org.apache.flink.table.data.RowData>

参数:

planner - The planner.

config - per-ExecNode configuration that contains the merged configuration from various layers which all the nodes implementing this method should use, instead of retrieving configuration from the planner. For more details check ExecNodeConfig.
