getDescription

public String getDescription()

Description copied from interface: ExecNode

Returns a string which describes this node.

Specified by:

getDescription in interface ExecNode<org.apache.flink.table.data.RowData>

Overrides:

getDescription in class ExecNodeBase<org.apache.flink.table.data.RowData>

translateToPlanInternal

protected org.apache.flink.api.dag.Transformation<org.apache.flink.table.data.RowData> translateToPlanInternal(PlannerBase planner,
 ExecNodeConfig config)

Description copied from class: ExecNodeBase

Internal method, translates this node into a Flink operator.

Specified by:

translateToPlanInternal in class ExecNodeBase<org.apache.flink.table.data.RowData>

Parameters:

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.
