public interface BaseDoubleColumnValueSelector
extends HotLoopCallee, BaseNullableColumnValueSelector

Double value selecting polymorphic "part" of the ColumnValueSelector interface. Users of getDouble() are encouraged to reduce the parameter/field/etc. type to BaseDoubleColumnValueSelector to make it impossible to accidently call any method other than getDouble(). All implementations of this interface MUST also implement ColumnValueSelector.
