translateToPlanInternal

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

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<T>

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.

checkAndConvertInputTypeIfNeeded

protected abstract org.apache.flink.table.types.logical.RowType checkAndConvertInputTypeIfNeeded(org.apache.flink.table.types.logical.RowType inputRowType)

Check whether the given row type is legal and do some conversion if needed.
