类 BuiltInScalarFunction

java.lang.Object

org.apache.calcite.sql.SqlOperator

org.apache.calcite.sql.SqlFunction

org.apache.flink.cdc.runtime.functions.BuiltInScalarFunction

@Internal
public class BuiltInScalarFunction
extends org.apache.calcite.sql.SqlFunction

This is the case when the operator has a special parsing syntax or uses other Calcite-specific features that are not exposed via SqlFunction yet.
