org.apache.flink.table.planner.functions.sql.SqlJsonObjectFunction

public class SqlJsonObjectFunction
extends org.apache.calcite.sql.SqlFunction

This class has been copied from Calcite to backport the fix made during CALCITE-4394.

TODO Remove this class with Calcite 1.27 and replace the SqlJsonObjectFunction in the SqlJsonObjectFunctionWrapper using the VARCHAR_NOT_NULL return type inference.
