public interface BaseFloatColumnValueSelector extends HotLoopCallee, BaseNullableColumnValueSelector
Float value selecting polymorphic "part" of the ColumnValueSelector interface. Users of getFloat() are encouraged to reduce the parameter/field/etc. type to BaseFloatColumnValueSelector to make it impossible to accidently call any method other than getFloat(). All implementations of this interface MUST also implement ColumnValueSelector.
