> Introduce getDescription, getOutputType, replaceInput methods for ExecNode
> --------------------------------------------------------------------------
>
> Key: FLINK-20512
> URL: https://issues.apache.org/jira/browse/FLINK-20512
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Planner
> Reporter: godfrey he
> Priority: Major
>
> We will introduce {{getDescription()}} method which returns the description
> information of the ExecNode,
> introduce {{getOutputType()}} method which returns the output {{RowType}} of
> the ExecNode,
> introduce {{replaceInputEdge(int ordinalInParent, ExecEdge newInputEdge)}}
> method which can update the input edge at the given index.
> Note: {{RelNode}} also has {{getDescription()}} method, so before we finish
> all separation work, we will introduce {{getDesc()}} instead of
> {{getDescription()}} to avoid compile error.
