[jira] [Created] (FLINK-20512) Introduce getDescription,
getOutputType, replaceInputEdge methods for ExecNode
godfrey he created FLINK-20512:
----------------------------------
Summary: Introduce getDescription, getOutputType, replaceInputEdge 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
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.
