Constructor Detail

DrillSqlOperator

@Deprecated
public DrillSqlOperator(String name,
                                    int argCount,
                                    boolean isDeterministic,
                                    boolean isNiladic)

Deprecated.

This constructor exists for the legacy reason. It is because Drill cannot access to DrillOperatorTable at the place where this constructor is being called. In principle, if Drill needs a DrillSqlOperator, it is supposed to go to DrillOperatorTable for pickup.
