Interface BuiltInSqlOperator

All Known Implementing Classes:
BuiltInSqlFunction, MatchRowTimeFunction, SqlTryCastFunction
@Internal public interface BuiltInSqlOperator
SQL version of BuiltInFunctionDefinition in cases where BridgingSqlFunction does not apply. This is the case when the operator has a special parsing syntax or uses other Calcite-specific features that are not exposed via BuiltInFunctionDefinition yet.

If SqlOperator were an interface, this interface would extend from it.
