[jira] [Updated] (FLINK-3736) Move toRexNode and toAggCall logic into Expressions

     [ https://issues.apache.org/jira/browse/FLINK-3736?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yijie Shen updated FLINK-3736:
------------------------------
    Description: Since we have a one-to-one mapping from Flink {{Expression}} to Calcite {{RexNode}}, and we will implement more and more expressions to make flink-table a full-fledged module, I think it's worthwhile to let each Expression take care of its own behaviour on conversion to RexNode.  (was: Since we have a one-to-one mapping from Flink Expression to Calcite RexNode, and we will implement more and more expressions to make flink-table a full-fledged module, I think it's worthwhile to let each Expression take care of its own behaviour on conversion to RexNode.)
